The ironically-named Fort Invincible is ambushed by an evil Apache chief and his gang of indians. The fort is preserved, thanks to the due diligence of Captain Richard Lance and a band of soldiers from a nearby fort. Lance is able to capture the chief, but instead of killing him, he follows orders and returns the prisoner to the fort. The captain’s insistence on following the rules has consequences, however, and the military soon decides the Apache chief needs to be transferred elsewhere in order to save their fort from vengeful indians. It’s a dangerous job, so Lance decides to handle it himself—that is until his superior makes him send his best friend, Bill Holloway instead.
After Holloway is killed on the mission, the other soldiers begin to resent Lance because they think he ordered the switch on purpose. In the meantime, Lance receives word that the Apache indians are planning a major attack on the fort. He handpicks a rowdy group of soldiers (many of which want to kill Lance personally) and embarks on a suicide mission to protect Fort Invincible from the onslaught of Apaches. —DVDverdict.com
