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. The film blends the same musical mayhem and satire that made the original a cult classic, featuring some fantastic rock cameos in the process. Will this concert be their triumphant return, or just another Stonehenge-sized catastrophe?
