Famy and McCoy are hired to assassinate a world famous scientist. They are sought by British security on the streets of London.

Sokarev reluctantly proceeds to his London engagement under the protection of veteran security agent Jimmy, an alcoholic with a maverick streak. The terrorists botch their hit and split up.

Wounded McCoy stays at the suburban home of Norah, a local girl who inexplicably loves the brutal killer. Police catch McCoy, and Jimmy pries out of him Famy's next plan: to kill Sokarev at Heathrow Airport. Jimmy leads his men in a race against time and manage to collar the Arab.
