Using the alias of "The Chicago Kid", Ben Wright trails Coyote Jack Roberts and his outlaw gang, the men who killed Ben's grandfather when they robbed the bank at Little Black Water, New Mexico Territory.

Ben has vowed to "get" every member of the gang, but he still has time to help persons in trouble, such as orphans.

As he trails the outlaws, he meets up with a Mexican gunfighter, The Angel of Death. She is also chasing the Roberts gang because of a raid they pulled at her family's ranch in Mexico.

They finally make their way to the Owl's Nest, an outlaw haven in the mountains north of Silver City. In a series of confrontations, blood will flow. Will it be outlaw blood, or the blood of The Angel and The Kid?
