Three friends from school, Thomas, Nils and Andreas, are still searching for love in their adult lives.

In Aachen ring the wedding bells. It will be the most beautiful day in the life of Julia and Alex. But Manfred, father of the groom and Kleinganove makes him a nightmare. A dead courier, a dorky mafioso, a neurotic old-68, sparkling diamonds and a waiting bride: A wedding that you do not want his worst enemy.
