Jake Blues is just out of jail, and teams up with his brother, Elwood on a 'mission from God' to raise funds for the orphanage in which they grew up. The only thing they can do is do what they do best: play music. So they get their old band together, and set out on their way—while getting in a bit of trouble here and there.
King Arthur, accompanied by his squire, recruits his Knights of the Round Table, including Sir Bedevere the Wise, Sir Lancelot the Brave, Sir Robin the Not-Quite-So-Brave-As-Sir-Lancelot and Sir Galahad the Pure. On the way, Arthur battles the Black Knight who, despite having had all his limbs chopped off, insists he can still fight. They reach Camelot, but Arthur decides not to enter, as "it is a silly place".
