Qila

When landowner Jagannath Singh (Dilip Kumar) is murdered, his twin brother Amarnath Singh (also Dilip Kumar) decides to investigate, and finds the list of suspects is seemingly endless. From Jagannath's own son Amar (Mukul Dev), to his abused wife, Suman (Smita Jaykar), to the woman he raped, Yamini (Rekha) and her brother Kundan (Malay Chakravarty), there's a long list of wronged people with a reason to want Jagannath Singh dead.
