An experiment in bovine genetic modification goes horrifically wrong in writer/director Billy O' Brien's debut feature. John Lynch stars as Dan, a cattle farmer in the remote Irish countryside, whose ex, Orla (Essie Davis), a veterinarian, has convinced him to take part in a profit-driven experiment on his cows, run by John (Marcel Iures), an officious scientist who seems very concerned with maintaining secrecy. Orla is conducting a routine check on a pregnant cow, & her hand is inside the animal, checking the unborn calf, when something bites at her. John is called to the farm, & reassures them that the safety checks were all okay. He's more concerned with the presence of a caravan just outside the farm occupied by Jamie (Sean Harris) & Mary (Ruth Negga), a desperate young couple who are apparently hiding out from something.
