There's a rather angry man by name of Joe, he's been shaped by past events and they bestow, a ruthless urge to find success, fiscal and personal progress, and he's found a girl who'll give him just the tow. Susan Brown is being courted by another, but Joe's target is for him to be the lover, her family oozes affluence, the father has great influence, although he's far too working class for Susan's mother. Into the works, a spanner enters and distracts, a married woman pulls Joe over to new tracks, Alice is somewhat mature, but she's opened up a door, and Joe's struggling to keep himself intact.
We follow Joe Lampton as he attempts to climb the social ladder shortly after the close of WWII. He's a dislikeable bloke, unstable, abusive with a very short fuse, most likely because of the life he's led to date, but still no excuse. He soon finds out that dreams don't come true, that happiness is fleeting and that the grass isn't always greener. Two outstanding performances from Laurence Harvey and especially Simone Signoret (watch her in Les Diaboliques if you haven't already), but this needs to be watched with the era it was written and subsequently filmed in mind, as it doesn't carry over well into more modern times and parallels.
