Children usually love to relax at summer camp. But Sarah didn’t like it right away at the Cold Lake camp. It was disgusting to even enter the dirty and slimy pond. And Sarah didn’t have a good relationship with the girls from the very beginning. They simply hated her. So Sarah decided to pretend as if she had drowned... And then everyone would immediately begin to feel sorry for her and want to make friends with her. However, things didn't turn out the way Sarah planned. Because at the bottom of a cold, dark lake a strange transparent creature was waiting for her, which pretended to be... alive.
