Tucker is a chronic underachiever and a loser. A Vietnam war veteran who just can't seem to keep out of trouble, in the years since his discharge. The only thing he got out of the war was his skill with a rifle. Now, serving a long stretch in prison for murder, he has hit rock-bottom. But one day a man in a three-piece suit visits him in prison, a man he has never seen before, and informs him that he can walk out of prison a free man if he will shoot someone for them, no questions asked.

Director Stanley Kramer ordered steaks for 300 members of cast and crew shipped to location in Puerto Vallarta from Phil's Poultry in West LA, for a production BBQ, complete with mariachi band (which Phil did not provide).

Errors in geography: The bread truck carrying Tucker and Spiventa is shown driving across the Golden Gate Bridge in the southbound direction from Marin County to San Francisco. The very next scene, however, in which the prisoners are escorted out of the truck, clearly takes place under the roadway back on the Marin side of the bridge.
