A Vigilante (15)

Sadie has managed to escape the steely grasp of her bullying husband. She has slowly rebuilt her life, improving her physical fitness with gruelling gym sessions. Sadie sleeps with a knife under her pillow just in case the spectre of her past materialises. She devotes her time to doling out brutal punishment to men who are terrorising their wives and girlfriends. Victims contact Sadie with the same cryptic message and provide her with enough information to help the terrified women strike back.
