When small-time mobster, Vito Scaldifieri, is framed for the murder of an undercover Federal Agent, he has two choices - face the death sentence or "sing" to the Feds for their case against mob boss Paulie DeMartino. Though telling all to the government goes against every fiber of his being, he knows it's the only way to save his life and, more importantly, guarantee the safety of his beloved wide Sharon. After a trial in which Paulie is indicted, Vito and Sharon are given new identities and placed into the Witness Portection Program. What they aren't told, however, is that in recent months, several mobsters under government protection have been assassinated in cities and towns all over the country. How they were being found and killed was anyone's guess. Jimmy Kerrigan, a tough, old-school newspaper reporter, begins investigating the Witness Protection Program killings.
