A queer slasher film starring Hannah Einbinder and Gillian Anderson, which has been winning over critics and audiences alike since its premiere at the Cannes Film Festival, where it won the Queer Palm. After years of sequels and a dwindling horror fanbase, Camp Miasma is entrusted to a young director keen to breathe new life into the genre. However, when she visits the film’s original lead, an actress shrouded in mystery, the two women are plunged into a bloody world of desire, fear and delirium. And a new kind of slasher emerges from the depths of the lake.
