A cabaret is used as a cover for drug trafficking, but the police are unable to uncover the means used to smuggle the opium. It turns out that one of the accomplices is repatriating the bodies of her compatriots who have died abroad and smuggling the drugs. A race is waged between the police and the culprits: the law triumphs.
