In Venice Beach, naive Midwesterner JB bonds with local slacker KG and they form the rock band Tenacious D. Setting out to become the world's greatest band is no easy feat, so they set out to steal what could be the answer to their prayers... a magical guitar pick housed in a rock-and-roll museum some 300 miles away.

Tenacious D fans will find this movie hilarious; everybody else will see only a low-brow concept movie and a small assembly of jokes stretched past the 100-minute mark.
