Described by director Michael Powell as being "about a chap who never paid for anything," Something Always Happens centers around an unemployed car salesman, Peter Middleton, who maintains an optimistic outlook despite his present circumstances. While this is all well and good, it isn't helping advance matters with his girl friend, Cynthia, who wants him to make more of an effort so they can get married. Capitalizing upon Peter's opportunistic streak, Cynthia persuades him to pitch one of his business ideas -- that petrol (or gas) stations will do better business if they are made more appealing to the customer - to Mr. Hatch, the wealthy owner of a car factory. The owner dismisses his idea, whereupon Peter pitches the same idea to a rival car factory. The rival hires Peter and he becomes a great success there. Employing deception, betrayal, disguises -- and a key withholding of information -- Peter's methods are not always honorable, but they are effective. In the end, even one of those outwitted by Peter recognizes his ability, clearing the path for a happy ending.
