Seven women stand in shock in a seedy hotel room; a man's severed head sits in the centre of the floor. Each of the women - the wife, the teenager, the ex, the journalist, the colleague, the friend, and the woman who raised him - has a very good reason to have done it, yet each swears she did not. In order to protect each other, they must figure out who is responsible, all while staying one step ahead of the police.

Against the ticking clock of a murder investigation, each woman's secret is brought to light as the connections between them converge to reveal a killer.
