A tanker truck crashes after a pursuit, and poisonous and explosive liquid leaks out. The dying driver warns of a second transport with Uli Schatz at the wheel. The poison is to be shipped illegally to Africa. Semir and André pursue Uli, who knows nothing about the deadly cargo or his hidden son. The truck's refrigeration unit breaks down, and the explosive cargo threatens to detonate in the heat - the truck must keep moving to prevent a catastrophe.
