Johnny Depp stars as notorious Irish-American gangster Whitey Bulger, who spent thirty years as an FBI informant while rising to the top of the Boston underworld, in this adaptation of the book by Dick Lehr and Gerard O’Neill.

In 1970s South Boston, FBI Agent John Connolly persuades Irish-American gangster Jimmy Bulger to act as an informant for the FBI in order to eliminate their common enemy: the Italian mob. The drama tells the story of this unholy alliance, which spiraled out of control, allowing Whitey to evade law enforcement while becoming one of the most ruthless and dangerous gangsters in Boston history.
