Trevor, Craig and Ben are all members of a band in which they all try really hard but yet fail to succeed to work together and play something that sounds half decent for the upcoming "Battle of the Bands" concert. One night after a lousy practice at Craig's place and a half a dozen of beers, Trevor walks home heading for an intersection when he suddenly gets hit by an ice cream truck, sending him tumbling down the street and falling unconscious. The next thing, he wakes up in the hospital with his friends next to him not remembering anything about who he really is or who the people around him are, but rather believing that he is some sort of a great composer from the 17th century called Canute Ironside. The story develops as Craig and Ben try to get their friend back to normal, dealing with the fact that he now speaks with a strange European accent, walks funny, tucks his jeans into his socks, does not recognise them, does not know anything about Rock and on top of all, they have a gig in a couple of weeks to which they must make it.
