After an invitation to ‘peaceful’ Camp Fish Head Lake, Ham and his buddies arrive expecting to be guests of honour. But there are no staff to be seen, and with kids (and their overprotective parents) arriving, they decide to just go with the flow. How hard can it be to keep a few kids out of trouble? But the camp turns out to be not so monster-free—and definitely not the kind of lake you want to go fishing in! Ham and his friends have their hands full as campers start to go missing and will have to work together and trust each other to figure out what’s going on—especially when old foes return.
