Because he wants his money back, he starts working for the racketeer gang and quickly adapts to the environment of big money, debaucherous parties, prostitutes, and police raids. During a deal, the police are called. Martin sees the television report about the search for Harry and Richard, so he immediately goes to the hostel to warn them. In the meantime, the VB arrive and run upstairs. Richard and Martin jump from the balcony, but Harry becomes dizzy and commits suicide. After the gang appears in court, only the boss escapes unpunished. Martin is told the truth about Eva: she is a prostitute. The film ends by the characters sitting in a car as the gates are closed.
