Synopsis

In a cheap hotel in Paddington await two men: in room 36, Mister Armstrong, a travelling lingerie salesman, prepares for the arrival of a prostitute. In room 38, Mister Connor, a professional hit man, awaits the arrival of Miss Woods, a traitorous MP delivering classified information. Unbeknown to Woods, her defection has been discovered: Connor's objective is to retrieve the microfilm - and kill her.

Opposite Connor's room, an arguing couple's fight results in his door number being damaged - it now also reads 36. The prostitute arrives, inadvertently entering Connor's room; he presumes her to be Woods. When she becomes too friendly, the mistake is exposed - Connor shoots her and bundles the body under the bed.

Woods arrives, but before Connor can obtain the microfilm, the prostitute's body is revealed. Managing to flee, Woods seeks refuge in Armstrong's room. Mistaking her for the prostitute, Armstrong forces himself upon her - resulting in his violent death.

With Woods discovering she's Iost the microfilm and Connor determined to find and kill her, a deadly battle of wits ensues...
