Plot

A cavalry officer posted on the Rio Grande is confronted with murderous raiding Apaches, a son who's a risk-taking recruit and his wife from whom he has been separated for many years.

Rio Grande takes place after the Civil War when the Union turned their attention towards the Apaches. Union officer Kirby Yorke is in charge of an outpost on the Rio Grande in which he is in charge of training of new recruits one of which is his son whom he hasn't seen in 15 years. He whips him into shape to take on the Apaches but not before his mother shows up to take him out of there.The decision to leave is left up to Trooper Yorke who decides to stay and fight. Through it all Kirby and Kathleen though separated for years fall back into love and decide that it's time to give it another try. But Yorke faces his toughest battle when his unorthodox plan to outwit the elusive Apaches leads to possible court-martial. Locked in a bloody Indian war, he must fight to redeem his honor and save the love and lives of his broken family.—Christopher D. Ryan <cryan@direct.ca>

Lt. Col. Kirby Yorke commands a U.S. cavalry troop north of the Rio Grande. Indians have been raiding and then fleeing south of the river into Mexico. Yorke is surprised when he learns that the son he has not seen for 15 years, Jeff, has flunked out of West Point. He's barely digested the information when his son shows up at the camp as a new cavalry recruit. His personal life gets even more complicated when his wife, Jeff's mother, Kathleen also shows up at the fort intent on taking her son home. As the situation increasingly deteriorates, the women and children are sent to safety but the wagon train is attacked and all the children taken forcing Yorke and his men to cross into Mexico to get them back.—garykmcd
