Point of No Return

Point of No Return is a movie starring Bridget Fonda, Gabriel Byrne, and Dermot Mulroney. A government fakes the death of a criminal to turn this young woman into a killer on its service.
Hardened criminal Maggie Hayward's consistent violence, even in police custody, ends in the execution chamber. However, top-secret US government agent 'Bob' arranges a staged death, so Maggie can be elaborately trained as a phantom killer and subdued into obedience.
