John and Michael are brothers, partners in crime who pay their way with cold-blooded murder and robbery. They're monsters created by a brutal father who taught them that people are just piggy banks. You need cash? Just break one open...

But the boys' violent lifestyle takes its toll on their relationship. Michael disappears leaving John to go solo and it's not long before he realises how empty and joyless his days have become.

Desperate for something to capture his interest, he gets his wish when he discovers his father had another family - a wife and a daughter. Suddenly John is a man on a mission. He's going to track down the sister he never knew he had...and kill her.
