Kylie, a troubled young woman, attempts to steal the safe from an ATM. Her accomplice knocks himself out while attacking the ATM with a sledgehammer, and, when she is slowed by attempting to save him, the police capture both. Due to her history of recidivism, she is sentenced by the judge to house arrest for eight months under the care of her mother, Miriam. Kylie does not get along with either her mother or her step-father, Graeme, both of whom she considers to be nothing but boring annoyances. A security contractor, Amos, explains that Kylie's ankle monitor will alert the police if she ever leaves the premises of her mother's house.
