The A-Team is an American action-adventure television series that ran on NBC from 1983 to 1987 about former members of a fictitious United States Army Special Forces unit. The members, after being court-martialed "for a crime they didn't commit", escaped from military prison and, while still on the run, worked as soldiers of fortune. The series was created by Stephen J. Cannell and Frank Lupo. A feature film based on the series was released by 20th Century Fox in June 2010.

The opening narration of 'The A Team' is:

"In 1972, a crack commando unit was sent to prison by a military court for a crime they didn't commit. These men promptly escaped from a maximum security stockade to the Los Angeles underground. Today, still wanted by the government, they survive as soldiers of fortune. If you have a problem, if no one else can help, and if you can find them, maybe you can hire... the A-Team."
