Schattenboxer (1992)

Eddi is just back in town after his imprisonment. He plans to free his African jail comrade Timpe, because the latter will get no asylum in Germany and probably be killed when sent to his country. When freeing Timpe at the airport, Eddi and his comrades find out that the police officers are smuggling drugs when escorting those who get no asylum back to their countries. Eddi decides to take advantage of the situation.
