Rippy

“Rippy's gone rogue.”

Maddy wants to know what happened to her father, so she heads to a remote Australian property where her uncle Schmitty (Michael Biehn) and aunt live with a mysterious houseguest named Stan (Mungo McKay). The discovery of a parasite in the water sets off a cascade of violence and mutation that spirals outward, unstoppable. The film moves with the logic of infection: once the damage begins, there is no stopping what spreads.
