When a bunch of ruffians rob a bank in the sleepy town of Alpine, it's only natural for the locals to be alarmed. But this gang and its leader, Cestus Calloway, are a different breed of outlaw. In fact, Cestus, known as the Robin Hood of the Rockies, distributes his loot to those less fortunate and rains stolen money down on the townsfolk. As if that isn't too good to be true, this gang holds to one important rule: Steal but don't kill.

All Alpine's Marshal, Boyd Cooper, wants is peace and quiet, not to get a posse together to track outlaws. However, when an altercation leads to the exchange of gunfire and the spilling of outlaw blood, he doesn't have much of a choice. The outlaws fear their reputation might be at stake, so they declare revenge on the tin stars of Alpine. They're mad enough to break their own no-kill rule, and Boyd Cooper knows things could end as bloody as they started....
