Filmmaker Julien Temple takes a look beyond the guise of the late, anti-establishment icon Joe Strummer to offer a warm portrait of the self-described "mouthy little git" who was born John Mellor and was destined to become the frontman for one of the most influential punk bands ever. A complex figure who would learn to use his gift for music as a means of decompressing his conscience, Strummer is revealed here through unearthed interviews and the illuminating recollections of his closest companions. At times idealistic to a fault, the flawed Clash singer/songwriter had a special gift for compelling listeners to think as they moved to the music. Vintage performance footage and excerpts from Strummer's popular BBC radio program offer the ideal musical backdrop for an affectionate tribute to a punk-rock legend.
