A group of young girls descend on a sleepaway camp where their days are filled with swimming lessons, friendship bracelets, and songs by the fire. Filled with excitement and nervous energy, they set off on an overnight kayaking trip to a nearby island. But before the night is over, they find themselves stranded, with no adults to help them survive or guide them home.

The Lost Girls of Camp Forevermore traces these five girls through and beyond this fateful trip. We see them through successes and failures, loving relationships and heartbreaks; we see what it means to find, and define, oneself, and the ways in which the same experience is refracted through different people. A portrait of friendship and of the families we build for ourselves, and the pasts we can't escape.
