The film stars Mithun Chakraborty, Ranjeeta, Jeevan, Jagdeep, Iftekhar, and Aruna Irani.

[2] Based on a spy thriller (with hero's code of Gunmaster G9), it was the first of two such films with Mithun in the lead, the other being Wardat.

The CBI Chief (Iftekhar) learns about this and calls for Officer Gopi (Mithun), aka Gunmaster G-9, to investigate into the matter.

The trouble starts when a plane flown by Captain Kapoor (Suresh Oberoi) is attacked by a stream of deadly signals force landing it.

After few interesting stunts, car-chases, fights, dancing with scantily-clad girls, some romance and comedy by agent Khabri (Jagdeep), they happen to meet the patchy-eyed SSO chief, Doctor Shiva (K. Balaji).
