A night-time chase. The dealers in their off-road vehicle are sweating bullets, because Diller and Kessel have them in their sights. A routine operation for the well-rehearsed duo, long-time friends who have always had each other's backs.

But instead of solving his problems, this bag plunges him into new, far greater conflicts - and takes his partner Diller and his family with him.
