Red Gully and his gang of brothers attack camped Indians and kill everyone except young boy Black Wing. His uncle Flying Cloud also survives but Black Wing does not know as he has already left to trail his father's killers. Chad, Joe and Erik are sent to bring Reese back from an extended weeks vacation and to get the Gully Gang. Reese, who is partying with three saloon girls, asks what day it is, realizes he is late getting back and heads for Laredo. Reese stops on the way where he is ambushed by Black Wing who shoots him in the buttocks with an arrow. The two quarrel at first and then establish a caring relationship as Black Wing eventually asks Reese to be his dad. Chad, Joe and Erik telegram their situation to the Captain and spend their time waiting with the saloon girls. The three trail the Gully Gang, running across three mail order brides who had everything they owned stolen from them by the Gullys. Black Wing finds the Gully's camp and shoots an arrow into it. Reese gets the drop on them but is captured when Red Gully grabs Black Wing and threatens to kill him. Black Wing escapes and runs for help, finding the other three rangers. The Rangers take out the gang and Flying Cloud, who has been trailing Black Wing, shows up. Reese is put in the guardhouse in Laredo and has low spirits until Black Wing and Flying Cloud stop by to say goodbye on their way to join their tribe in Oklahoma.
