you're an extra grams Gramps can you hear me come on come on I did not just dream you I didn't did I we all heard your grandfather Aunt yes not dreaming crabs are you eating me over wait but if it is a dream no one in the dream would admit it thank me you needed that definitely awake thanks sonar something's out there [Music] sir oh that explains why we can't hear them they've drifted from this position should have a visual soon [Music] huh no that's too big way too big to be their sub anything they can made see this [Music] someone else in this family suggesting it's alien it's not alien Nautilus a nautilus the little shell creature yes but this one isn't little it's a monumental the radio signal came from here and if we can't hear them outside grandparents have to be inside my family are explorers we have been for Generations While others look up to the Stars we know there are an infinite number of things that shine in the darkness below there are things looking in the seas that long ago vanished into myth my family are the neptuns and we explore the [Music] thank you [Music] Rover calling on all channels can anyone hear me still nothing he must be inside it will why can't we come too it's a wake Fontaine clearly awake I'm sorry it's just too dangerous who Ranger well I do Fontaine just kind of pulls faces see if we have to go inside the creature we're qualified there done that and we need as backup backup we're front line it this is New Territory I'm not risking more people I love to find them understand oh man how are you gonna get in certainly not into that mouth no chance of surviving that but there are other places they could be any one of these craters or somewhere in the mantle cavity or under the hood [Music] that's a lot to search sounds like you could use some backup nice try aunt Nature's perfect creature oh yeah I remember Graham Grant not a lie get my vote for Nature's perfect creature perfect Design This shell is amazingly tough like underwater armor I'll probably build myself underwater armor one day sure you will Aunt don't doubt him Fontaine if you like your father any doubt will just make him more determined would you even use underwater armor for for underwater protection now this armor hasn't changed in 500 million years it feels like your grandpa has been changing 500 million years either doesn't make him perfect [Laughter] I miss them and we just found a crater we're going to investigate [Music] sonar isn't picking up anything unusual in here and there could be hundreds of these holes we're not tense at all [Music] those Siri grab food and if we're grabbed we're done I'll steer clear all these openings they could lead anywhere did you do that no there's a current bully it's dragging us in it's the hyperdome sucking in water we need to get away from it full power it's not enough we can't gotcha great movement I'm warming up today's backup thing I'm at full reverse here and we're only just holding you at least we're not moving any closer hold on the suction's just gone Rover this is Aaron ax can you hear me it sucks in water then it spells fell down quick what go there's nothing on Sonar mom dad can you hear me [Music] Mom Dad come in [Music] Aaron ax to Rover come in mom dad can you hear us how can a creature that big just vanish it didn't vanish it's not magic I don't think we can rule that out it just moves really fast how it doesn't even have fans when the hypnome blasts out water it gives a nautilus jet propulsion jet propulsion cool travels backwards look yes that direction I hope okay lights are functional air purifier operative all systems seem to be normal were minus an arm and it's do read me over the shell could be too thick to get a signal out I don't know what I'm doing here we may have gone too far already a few degrees often we never see it how far could it go in one burst you ask as if I'd know that I'm perpetually hopeful [Music] sonar yes hey I think I see something sonar reads two degrees to starboard it's something our Monumental something totally Armani mentioned aeronax to Rover Aaron ax to Rover are you reading me over there next we're reading you are you okay we're good are you okay we're fine you're just in a very weird place well look it's an eepard [Music] looks like your parents emergency distress Beacon we're not detecting a signal from it the battery is probably dead so if the Epub is there then cramps and Grandma was sucked into that Hyperdunk too yes we could be close that wall it looks a lot closer than it was are we drifting nope it's moving towards us fast anyway I'll run it we can try mom dad you okay Rover Come on talk to me backup time let's do it [Music] stay here Jeffrey you're Rebecca you're right you're no one's backup your front line come on buddy we have to avoid the Siri way to avoid them if we're heading straight at them it's okay not a LIDS are opportunistic feeders like me sure sure but quieter they catch slow moving things go faster at top speed we'll be through before the Siri can react you sure 14 you sure all this is one big muscle imagine a flexible bladder that draws in all this water try to rock us free come on okay we're moving slightly excuse me that was the backup arriving just when you needed us excellent right we definitely do push [Music] daddy bear again all right yes great job I'll keep some distance from that wall the wall that just goes on forever something metallic ahead metallic sounds promising submarine it's them oh okay there comes a mess but that doesn't mean I hope they're okay [Music] good this is Will can anyone read me [Music] [Music] yeah did you see that I definitely saw something dead it sure is well I'm here too oh well all right talk I want to hear your voices Mom are you both okay we're a lot better now well we'll Define okay you sound great and you're here Fontaine I'm here we wouldn't miss this reunion for the world it's been so long you know we've been in here for four months ever since we left lemuria I need to find you we knew you would too never gave up hope we're okay for now creature moves we get we get I don't think I think our oats longer yeah yeah I'd say we got here just in time but how do we get you out not easy the airlock hatch is broken and rusted shut I'll try to loosen it [Music] okay there's no way out there [Music] do you have an escape capsule yes but the ejection mechanism is broken we can't use it so we have to breach the hull have you got scuba gear sorry will our air tanks were in the forward section when it got crushed we can't breach the hull well this sub's not moving on its own then we move it if we pull this up free then we can all push it out that's a great idea it is everyone grab something soft we have to do this gently one two three stop this thing is too fragile there's a hole in section c we know we know it's okay we we're in section D now but the bulkhead has a small leak you should move through the cargo bay to the battery room we're trying again everybody one two three [Music] I felt that we moved gently does it oh no I'm feeling a current the water pressure's Rising the Monumental point of moving here I don't know if our stuff can survive that we need to get you out of here now everybody get into position to push pressure's still Rising it's drawing water in then let's go [Music] I think you should move to section g it's stronger you're in my mind moving already man all right [Music] everyone we need to keep accelerating constantly yes we have to be going as fast as we can to get past the series we're moving at 10 knots now keep accelerating hey did you find any of the clothes we dropped we did in all parts of the globe very confusing 15 knots keep moving we tracked this nautilus's movements across the globe there's a pattern you can tell me all about the pattern as soon as we're out of here it looks later ahead straight for the center we need to get up now 25 knots keep accelerating almost there oh no you don't I've got this in case anything happens you need to know about holy keys not now we can't shift it's it's okay sir I understand is there anything to protect you if we love you we love all of you too wait armor armor you need underwater armor Gramps go to can anyone hear me [Music] mom dad [Music] oh no can anyone see them yet there's nothing come on they made it they're here somewhere [Music] what's wrong Jeffrey can you hear something wow guys down here quick what's that the escape capsule looks like the photation system was damaged did they make it in I don't know let's go [Music] please please [Music] Mom well underwater armor for underwater protection could call it knew you'd make it Gramps dad never gave up searching of course he didn't [Music] find what's lost huh aunt who's this Jeffrey arguably the most important member of the family he was the one who found you thank you Jeffrey everyone what's that [Music] oh you need to see this [Music] it's back and it's beautiful listen in lemuria we deciphered a legend lemurians believed a key to the Sea could balance the oceans how could one thing balance the oceans no idea but we think the Nautilus is trying to find this key it's been moving with purpose all over the world is that the pattern you mentioned yep oh look oh no not again it's vanished again we have to find it how we have no idea where it went unless someone put a tracker on it Fontaine you did initiative right brilliant that's my granddaughter awesome so let's find that key to the Sea reunited necton family set sail hey that's my line mine first no way been doing it for years oh okay hey wait how about we say it together you're on reunited nectins [Music] come here [Music]
