When cafe worker Alanah is sexually assaulted at a party, her friends led by her boyfriend Martin, decide to mete out mob justice. The rapist is accidentally killed and the panicked group decide to imitate the grisly M.O. of a local serial killer known as The Weaver, for his prediliction for sewing shut the mouths of his victims.
The group struggle with guilt and the stress of potential discovery while Alanah tries to piece her shattered life together. Martin, however, shows a growing obsession with the killing and may have been fundamentally changed by the experience.
Now, the group find they may have to kill again to protect their secret.
Meanwhile, The Weaver does not take too kindly to being framed...
