Di belakang tabir (1970)

Osman was released after serving a ten-year prison sentence for a murder he did not commit. Two young men, Ali and Hassan had arrested Osman after he was released from prison and were brought to meet their leader, Karim who is also Osman's brother. Osman was beaten until he passed out and thrown into the river. ASP Azman was assigned to investigate the matter. Faridah, ASP Azman's wife, came across Osman when she went to the clinic that happened to be treating the injured Osman. Osman suspects that Faridah is actually Hamidah, his girlfriend before being imprisoned. Osman tries to prove that Hamidah is impersonating Faridah, and that everything that happened has something to do with the mafia group led by Karim. ASP Azman also suspected his wife who behaved like she was hiding something after Osman's presence.
