C.I.D (1956)

When the editor of a crusading newspaper is murdered after threatening to expose a powerful criminal, Inspector Shekhar takes up the case. He finds a witness and gets close to the man behind the crime, but the gang strikes back, and soon Shekhar himself stands accused of murder. With help from Rekha, the police commissioner's daughter he loves, and an unexpected ally from the enemy camp, he races to prove his innocence. Produced by Guru Dutt and directed by Raj Khosla, C.I.D. was a big hit of 1956 and introduced Waheeda Rehman to Hindi cinema. O. P. Nayyar's songs, including Leke Pehla Pehla Pyar, Aankhon Hi Aankhon Mein Ishara Ho Gaya and Johnny Walker's Yeh Hai Bombay Meri Jaan, are classics.
