The last days of six inseparable friends, each of whom has paranormal abilities, were spent in search of an answer: what kind of strange experiments is their chemistry teacher conducting on the lake? Of course, no one was going to follow him in a crowd. But it wouldn’t hurt to monitor his movements and actions! Having distributed the responsibilities, the friends begin to “spy.” Imagine their amazement when the chemist, having once again gone to the lake, approached the water and patted it with his hand. And immediately out of it appeared... a huge head of some kind of amphibian mutant. Not just one! What's going on here?!
