The fate of Mackenzie's Raiders hangs in the balance when one of their members is captured south of the Rio Grande while attempting to rescue his injured brother. The trooper is court-martialed and if he saves his neck by testifying he was under orders to cross into Mexican territory, it would mean the end of Colonel Mackenzie's career and the start of a war between the U.S. and Mexico.
