Mike McClure had been a deputy sheriff for only a week when U.S. Marshal Jesse Cole recruited him for a dangerous undercover mission to infiltrate the hired guns who were harassing the homesteaders of Harmony. But in a dreadful night of bloody carnage the mission ended in failure and with the marshal dead, Mike had to flee for his life.

To escape from the gunslingers on his trail, Mike holed up with Brandon Webb's Wild West Show where he assumed a new identity. But no matter how successful he became in his new life, Mike could never forget the terrible events he had witnessed.

One day he must return to Harmony and call upon all his gun skills to bring the guilty parties to grim justice.
