The film begins in Camden Town, London, on a grey day in January 1976.
Three friends, Lee Thompson, Chris Foreman and Mike Barson, start to play music together.
Along the way their band suffers numerous arguments and changes in their line-up before finding success in the final scene, with a full piece Madness going out to a packed, screaming arena.
Film from the first four days of the shoot was overexposed in the development lab which necessitated reshoots.
The film is available on DVD, with commentary by Dave Robinson and Madness guitarist Chrissy Boy.
