"This Is Spinal Tap" shines a light on the self-contained universe of a metal band struggling to get back on the charts, including everything from its complicated history of ups and downs, gold albums, name changes and undersold concert dates, along with the full host of requisite groupies, promoters, hangers-on and historians, sessions, release events and those special behind-the-scenes moments that keep it all real.

SPINAL TAP is back! After a 15-year hiatus, David St. Hubbins, Nigel Tufnel, and Derek Smalls are drawn back together for one last concert. Documentary filmmaker Marty DiBergi returns to explore what the band members have been up to and immortalize the concert reunion. The film blends the same musical mayhem and satire that made the original a cult classic and features some fantastic rock cameos in the process. Will this concert be their triumphant return, or just another Stonehenge-sized catastrophe?
