Peter Strange is an idealistic young police recruit who gets mixed up with the machinations of the tough and jaded Scotland YardDetective Sergeant Pierce. Pierce is trying to arrest a gang for drug smuggling and later murder, but is thwarted respectively by a corrupt colleague and an unconvincing witness. Strange is shocked by finding the dead body of a murdered informant he knew and is himself brutally assaulted. Meanwhile, Strange is having an affair with Frederika, a minor who he does not know is part of a pornography ring; her supposed aunt and uncle film and photograph her sexual encounters from behind a one-way mirror. Pierce obtains copies of photographs of Strange's sexual encounter with Frederika and threatens to expose him to his superiors, ending his career, unless Strange plants some heroin on one of the gang. Strange reluctantly agrees, despite planning to leave the force anyway, as he is disillusioned by the failure to catch and convict the drugs gang. Pierce's planting of evidence is revealed and he is convicted of perverting the course of justice and jailed.
Allmovie wrote: "a fragmentary "'60s" interpretation of a straightforward Bernard Toms novel...Like many British films of its period, it seems more concerned with inducing pop-art headaches than simply telling its story.
Time Out wrote: "a well-written anecdote about police manners and methods, straight out of some TV cop series, but as viewed by Greene's wilfully wayward camera, it becomes a bizarre, quirkishly funny thriller which laces its documentary surface with a fine grain of fantasy. Much of Greene's later work disappointed, but here he displays a visual flair that would not entirely have shamed Welles in his Lady from Shanghai mood.
The New York Times wrote: "If the muscular and sexy goings-on are excessive and irrational on occasion, some of the principals lend credible, physical support to their characterizations. Michael York...is properly personable and confused as the harried Strange. Susan George, a comparative newcomer who is pert, snub-nosed and pretty, makes eroticism a pleasure, even if her sudden switch from promiscuity to Strange's everloving girl, remains a mystery. Jeremy Kemp is convincingly neurotic as the indomitable sergeant...They all prove that "The Strange Affair" is where the sensational action is, even if it is entirely strange and unbelievable.
