Generally liked shipping employee Tobias Blum assumes a prank went wrong when locked all night into a refrigeration container, in ER for frost treatment. Mattes realizes it was no accident, but Blum's jacket with cellphone being missing, he borrowed one from Karsten Kramm's 50 owner-manager Oskar Politz, who may be the real target and whose wife is known to Hans and obsessed Franzi as abuse victim, still refuses to file a complaint, but becomes the victim of an inefficient car bomb. Tobias has an affair with Kramm's wife, while the workaholic elder partner refused to accept a lucrative bid as Oskar wants most of all. Hans is tired of Franzi's immature emotional attitude, barely in time to prevent the next crime being deadly.
