Would you be willing to walk away from everyone and everything you've ever known in exchange for your safety? This is the question facing career criminal Bobby "Bats" Batton (Tom Sizemore); on the outs with the mob and facing prosecution for a number of serious crimes, Batton is offered a deal by the FBI in which he will be given immunity in exchange for testifying against his former partners. However, Batton will have to join the Federal Witness Protection Program, which means that he, his wife, and his children will never again see their friends and family.

After a brief flash-forward to Frank Sinatra as an old man, saying "I miss my guys," the movie's main narrative begins during high points in the solo careers of the Rat Pack: Dean Martin has become a big success despite the breakup of his partnership with Jerry Lewis; Sinatra's career is at its peak; Sammy Davis, Jr., is making a comeback after a near fatal car crash, and standup comic Joey Bishop is gaining exposure as an opening act for the other three. The Pack becomes complete when Sinatra reconciles with actor Peter Lawford, who has been ostracized since being seen out publicly with Sinatra's ex-wife, Ava Gardner.
