Having relinquished Fort Holman to the Confederacy without a shot being fired, Col. Pembroke (James Coburn) is in danger of a court-martial finding him guilty of treason. To escape certain death, he agrees to try to retake the lost fort using the services of seven men already condemned to death. The men are no happier to serve under him than he is to have them, but despite their own quarrels (and threats on the Colonel's life), they arrive at the fort and mount their attack. Though this western was produced by a European syndicate, it has an English soundtrack.
