Jon and Ponch volunteer to escort veteran truck driver Charlie Davis and his daughter Robbie on a 14-mile journey that could end in disaster at any second. The cargo is unstable liquid chlorine and the obstacles include roads damaged by heavy rains, a multiple car pile up, an escaped tiger, a town that won't permit the convoy to drive through, and their worst peril-hot, sunny weather that could cause the chlorine to explode with the force of nitroglycerine.
