Hitman Jef Costello is a perfectionist who always carefully plans his murders and who never gets caught. One night however, after killing a night-club owner, he s seen by witnesses. His efforts to provide himself with an alibi fail and more and more he gets driven into a corner.

Declan Patrick MacManus (born 25 August 1954), known as Elvis Costello, is an English singer-songwriter. He came to prominence as an early participant in London's pub rock scene in the mid-1970s and later became associated with the punk/New Wave genre. Steeped in word play, the vocabulary of Costello's lyrics is broader than that of most popular songs. His music has drawn on many diverse genres; one critic described him as a "pop encyclopedia," able to "reinvent the past in his own image".
Costello was born Declan Patrick MacManus in St Mary's Hospital, London, the son of Lilian Alda (nee Ablett, b. 1927, Liverpool) and Ross MacManus, a musician and bandleader. He is of Irish heritage. Costello lived in Twickenham, attending Hounslow Secondary Modern School, which is now St Mark's Catholic Secondary School, in neighbouring Hounslow. With a musically inclined father (who was a jazz trumpeter and sang with The Joe Loss Orchestra), Costello's first broadcast recording was alongside his dad in a television commercial for R. White's Lemonade (I'm a Secret Lemonade Drinker). His father wrote and sang the song; Costello provided backing vocals. The advertisement won a silver award at the 1974 International Advertising Festival.
Costello moved with his Liverpool-born mother to Birkenhead in 1971. There, he formed his first band, a folk duo called Rusty, with Allan Mayes. After completing secondary school at St. Francis Xavier's College, he moved back to London where he next formed a band called Flip City, which had a style in the pub rock vein. They were active from 1974 through to early 1976. Around this time, Costello adopted the stage name D.P. Costello. His father had performed under the name Day Costello, and Elvis has said in interviews that he took this name as a tribute to his father.

In South Boston, the state police force is waging war on Irish-American organized crime. Young undercover cop Billy Costigan is assigned to infiltrate the mob syndicate run by gangland chief Frank Costello. While Billy quickly gains Costello s confidence, Colin Sullivan, a hardened young criminal who has infiltrated the state police as an informer for the syndicate, is rising to a position of power in the Special Investigation Unit. Each man becomes deeply consumed by his double life, gathering information about the plans and counter-plans of the operations he has penetrated. But when it becomes clear to both the mob and the police that there s a mole in their midst, Billy and Colin are suddenly in danger of being caught and exposed to the enemy-and each must race to uncover the identity of the other man in time to save himself. But is either willing to turn on the friends and comrades they ve made during their long stints undercover?
