Johnnie Callum was a half-grown boy when Donovans riders stamped his parents homestead flat and sent him running terrified into the night. He ran far and fast over the trackless range that was Donovans empire and fetched up in the hands of Josh Manders, a brutal sheepherder. Manders worked him hard and in six years came near to breaking Johnnies spirit. But not near enough. Finally, there came a day when Johnnies resentment took charge and his big, bony hands wrapped around Manders throat in an unshakable hold. Johnnie took Manders horse and then worked for Sam Stevens. But when Donovan was all set up to wipe out Stevens ranch Johnnie began to get gun-minded!
