From the moment of climax we see couples in the sweaty, regretful, nervous and often unsatisfying aftermath of sex.
Hanna just wanted a one night stand. Alfie has other ideas.
Sian and Liam are at university together.
Amit and Paul are in a tent at a festival.
Julia has just slept with her son's best friend, Ryan.
Ella is annoyed at Sam for playing a computer game straight after sex.
We get to meet three of the couples again, following some 'quickies'.
