Four recruits arrive at Kimberley station to undergo training at the local army camp. Soutie, Liebling, Tiny and PP soon become friends as they are put through their paces by the sergeant. They all volunteer for border duty, where they are joined by Chico, a black tracker, and are sent out on patrol. After they come upon a murdered farm family, their radio is destroyed by enemy fire and they are required to find their way back to base camp. In the ensuing skirmishes some of them perish.
