Desperate Measures (1998)

San Francisco police officer and widowed father Frank Conner is in a frantic search for a compatible bone marrow donor for his leukemia-stricken son, Matt. In desperation, he breaks into FBI headquarters and finds a perfect match. Unfortunately, it is Peter McCabe, a sociopath who is serving life in prison for several murders. During his time in prison, the brutal, cunning McCabe has attempted escape and killed several guards and fellow prisoners, and must be kept in multiple restraints when out of his isolation cell. McCabe initially shows little interest in helping Conner, but later finds an opportunity to turn the situation to his advantage and devises a plot to escape. Biding his time, McCabe plays chess against a computer, easily defeating the program, and expresses the need for a challenge akin to Garry Kasparov or Deep Blue. Meanwhile, Conner, along with police captain Cassidy and Matt’s physician, Dr. Hawkins, prepare for McCabe to be transferred to the hospital for the transplant.

At the hospital, McCabe is given a sedative. With the aid of a counteracting drug he had obtained from a fellow inmate, McCabe slips out of his restraints, attacks the guards and attempts to escape. Conner and a fellow officer corner him, but McCabe holds a scalpel to Hawkins’ throat, prompting Conner to drop his gun. The other officer gets the drop on McCabe, but Hawkins warns the police that if he dies, his bone marrow becomes useless. Conner stands in the way of the other officer; McCabe takes his gun and shoots the officer.
