Bathtub Shark Attack

A couple, battered by life's disappointments, jumps at a suspiciously cheap apartment. The initial days feel like a hard-won sanctuary, until gurgling echoes from the bathtub drain shatter the calm. What stirs within the building's ancient pipes is no mere clog, but a primordial predator awakened from an eons-long slumber, now ravenous. Each relaxing bath morphs into a liquid deathtrap, their bargain home becoming a hunting ground where the water itself turns against them.
