In Minnesota, 1865. At the end of the Civil War, a band of ex-confederate soldiers have, after getting hold of a shipment of rifles and killing the four men guarding the cargo, split up after a dispute. The two brothers Bob and Ben Morgan who killed the gang leader's brother Jake Murphy are pursued by the militia and are surrounded in a cabin where Ben Morgan is shot dead and Bob Morgan is severely injured. Bob Morgan takes refuge with a Nordic settler family. The son, John Peterson, rides to the nearest town to get a doctor who can help Bob Morgan who is telling about his pursuers. Frank Murphy and his gang find Bob Morgan at the settler family and kill him and massacre the family before burning down the farm. When John Peterson returns with the Doctor, he finds his dead family and decides to take up the hunt for the perpetrators and take revenge on them.
