The battered corpse of Patrick "Paddel" Borowski MD is found on a market square in Hamburg. His three buddies, Jörg Kittel, Andy Jansen and Hans Peter "HP" Himmelreich, also dressed in flamingo costumes for his bachelor party in the Kiez quarter, allegedly can't remember losing him, let alone the murder. Borowskis cellphone pictures aren't helpful, but blood on his costume indicates a fight. Kittel merely admits a 'silly conflict' with the former medical practice partner. Reconstrcting the night, SOKO cops find the quartet won lots of cash in a casino, which is gone. A homeless beggar found outside actually stalked them on the fatal night, and lost everything after the death of his wife of Paddel's operation table.
