In a small North American town, Martha and Kyle work in a doll factory. Martha nurses her old father and usually gives a lift to Kyle.
When the young single mother Rose is hired to work at the factory, she is befriended by Kyle and Martha. In a Friday night, Rose hires Martha as babysitter and Martha finds that she is dating Kyle.
Rose returns back home early after stealing Kyle's savings, and Martha witnesses her ex-boyfriend Jake accusing Rose of stealing weed and money from his house.
On the next morning, Rose is found strangled in her house and Detective Don Taylor interviews Jake, Kyle and Martha along his investigation.
