Slim and Jess are tracking a Jersey milk cow that someone has stolen. They track it to their homesteader neighbor Roy Allen's farm. There they are ambushed by a group until Allen tells Gil Craig and his men to back off. The cow was borrowed due to their hungry baby. It's the sod-busters against the ranchers and the homesteaders have hired Gil Craig and his crew to protect them against cattlemen intent on driving them out of Laramie. Gil Craig has a different agenda and it involves starting a range war instead of stopping it. Slim and Jess are trying to keep a lid on a volatile situation, which is only made worse when rancher Luke Rawlins is murdered and the homesteaders are blamed. Luke was wanting to bring in hired guns from Texas which Slim was trying to stop. The Laramie Basin is in danger of blowing wide open and its up to Slim, Jess and the homesteaders to get to the truth behind the murder and Gil Craig before it's too late.
