Septic Man

In this nightmarish body horror film, a sewage worker's descent into madness is triggered by a sinister trap that leaves him submerged in a septic tank filled with rotting corpses, unleashing a hideous transformation that forces him to confront his own humanity and team up with an unlikely ally: a docile Giant. As the toxic sewage coursing through his veins twists his body into a grotesque parody of its former self, Septic Man must confront the madman responsible for his predicament, Lord Auch, in a battle to survive and reclaim his sanity.
