"The Law of Murphy". It sounds like a crap Hollywood movie, starring Colin Farrell as a hard-drinking Boston cop, distracted by complications regarding visitation rights following the collapse of his marriage and the loss of contact with his 8 year old son. When a notorious drug baron, Van Gaal (Steven Berkoff), kills Murphy's ex-cop father-in-law, O'Callaghan (Martin Sheen), the troubled maverick is plunged into a complex and dangerous case that could lead to salvation or, just as easily, death.
