On the night of her wedding, Jade finds herself waking up next to her deceased husband, having barely escaped an assassination attempt by the criminal family she had run away from just weeks earlier. Desperate for revenge, she trades her wedding ring for a .357 Magnum and attempts to kill one of the family members, but fails. Fortunately, a Vietnam Veteran known as “The Hammer” steps in, completing the kill and saving her life. Over the following year, Hammer trains Jade to become a precise assassin. On the anniversary of her wedding, she sets out to make each family member pay for their wrongdoings, armed with six bullets, each symbolizing her quest for vengeance.
