In a desolate and economically devastated town, a single mother named Billy struggles to make ends meet while taking care of her two sons, Bones and Franky. Bones, the elder son, spends his days scavenging for valuable copper in abandoned houses to help his family. During one of his explorations, he stumbles upon a mysterious underwater town, which is said to hold a dark and magical secret. This discovery coincides with Billy finding work at an eccentric nightclub, where she becomes involved in increasingly bizarre and dangerous activities. The club's owner, Dave, offers her dubious opportunities that promise quick money but lead her into a nightmarish world.

Bones' persistent curiosity about the submerged town puts him in conflict with Bully, a violent local thug who controls much of the town through fear. As economic pressures mount, Billy and her sons find themselves entangled in a web of sinister happenings and must navigate their way through a series of harrowing events if they hope to survive. Amidst the decay and abandonment, both Billy and Bones pursue threads of hope and resilience while uncovering secrets that could either save or doom them.
