England's loudest and most punctual band is back! After a fifteen-year hiatus, David St. Hubbins, Nigel Tufnel, and Derek Smalls aka Spinal Tap are drawn back together for one last concert. Documentary filmmaker Marty DiBergi returns to explore what the band members have been up to in the years apart and immortalise this epic concert reunion. The long-awaited new film, a direct sequel to 1984's This Is Spinal Tap, blends the same musical mayhem and satire that made the original a cult classic and features some fantastic rock cameos in the process, including Sir Paul McCartney, Sir Elton John, and more. Will this final concert be their triumphant rocking return, or will it be just another Stonehenge-sized catastrophe?
