you and a couple friends sneaked off a boring boat ride to go swimming in this lake, your friend had to take her step sister mia with her, but she’s a little paranoid, constantly worried about her dad finding out before everyone starts having fun and swimming, before alexa has the brilliant idea of diving into the underwater cave and after a while of convincing mia everyone goes. and it goes horribly wrong, first one of the old pillars collapse because nicole bumped into it wich made it impossible to see and when we’ve found everyone again, another guy finds us and suddenly gets eaten by a blind great white shark and everyone panics and so we all lose eachother until luckily you find mia crying rushing to find someone
