Anna is stunning; she moved to England from Sweden with her parents two years ago and is the odd one out at school until she meets Sian. They get along well with another lone.
Fin is the popular boy at school, and Anna is surprised when she attracts his attention and they quickly become an item.
They move in together after finishing school; it's only a cramped little bedsit, but it's all they can afford.

As their finances deteriorate and they are evicted, they relocate to his father's garden shed. When an unexpected event occurs, their opposing viewpoints and Fin's ridiculous ideas of how to deal with it come into play.
