There, they will deliver desperately needed supplies, but only if they can make it through the wolfpack of German submarines that awaits and outnumbers them in the perilous seas. For forty eight hours, Krause will play a desperate cat and mouse game against the submarines, combating exhaustion, hunger, and thirst to protect fifty million dollars' worth of cargo and the lives of three thousand men.
