Riff-Raff(1991)

Stevie, fresh from prison in Scotland, finds a job on a London construction site. The working conditions are poor and most of the men are working under aliases, due to immigration status and to not conflict with their "signing on" for unemployment benefits. Some coworkers help Stevie secure housing, squatting in a council estate. Then Stevie meets Susan, from Ireland, who's struggling to be a professional singer.
