Contrary. Passionate. Outspoken. Across their 45-year career, The Oils helped shape modern Australia with anthems like US Forces, Beds Are Burning, Blue Sky Mine and Redneck Wonderland. Featuring unheard interviews with every band member, unseen live and studio footage, alongside signature moments like the outback tour with Warumpi Band, their Exxon protest gig in New York and those famous Sorry suits at the Sydney Olympics, this film traces the singular journey of Australia's quintessential rock band. The Hardest Line tells Midnight Oils trailblazing story for the first time ever on film.
