Plot
In Summer 2008, Sean Conklin and his classmates, pretty and kind Tracy Miller who he has a secret crush on, her boyfriend, irresponsible prankster Tyler Shuman who had no clue about his friend's hidden affections for his girl and their other friends: thoughtful Bruce Delroy and his girlfriend, tough and headstrong Ruthie Semple decide to spend their last weekend together at a local lake after graduating from high school. Shortly after arriving, they head into the water, but Sean suddenly sees some apparently large tentacles splash out of the water, but no one else does and he dismisses it at first. Tyler finds a canoe and proposes that they go out to a floating platform in the lake to spend the rest of the day. Sean and Tracy discuss their future as they row out to the platform. Tyler attempts to scare them by pretending something has grabbed him and pulled him under, but they easily predict when he would resurface. As the day progresses, Ruthie is suddenly pulled underwater, and the group panics, but it turns out to be Tyler playing another trick.

They scold him, and Tyler angrily leaves in the canoe, leaving no easy way for the others to return to shore. Sean tells them not to worry, as Tyler will probably return, but they suddenly hear a yell and see that Tyler is missing again, and the canoe has been suddenly capsized. They immediately assume that he is trying to play a prank on them again, but Bruce decides to see if he can find him. After swimming over to the canoe, he says that he cannot find Tyler, and suddenly starts yelling, claiming something is grabbing him from underwater, and disappears as well. Sean confides in the remaining two that he saw the tentacles from before, but they have no way of escaping from the creature and resort to yelling for help for hours as night falls. As tragically as fate has it, what appears to be a giant octopus, strikes again, grabbing Ruthie and taking her down into the dark, cold depths of the lake. Sean and Tracy conclude that they have to try to swim to shore, or the creature will kill them anyway, but are attacked as they attempt to make the crossing. However, they were found on the shore, having survived drowning and were treated for exhaustion, shock, and unidentified blister-like wounds all over their bodies. The bodies of Tyler, Bruce, and Ruthie were never found.

Clips in the episode discuss known cases of animals adapting to environments other than their own, including freshwater jellyfish, and the abilities of octopi.
