Chris Cole (Mark Wahlberg) is a Pittsburgh fanatical admirer of a 1980s heavy metal band called Steel Dragon. By day, Chris is a photocopier technician and by night, he is the lead singer of a Steel Dragon tribute band called Blood Pollution (the name is taken from a Steel Dragon song).Internal struggles among the actual Steel Dragon band members culminate with the firing of their lead singer, Bobby Beers (Jason Flemyng), and the starting of recruitment sessions to find a new vocalist.

After hanging up on Kirk once, thinking he's being made fun of, Chris ecstatically agrees. At the studio, he meets the band, as well as learning that Bobby Beers was fired because he was a closeted gay, and gives an outstanding performance of "We All Die Young" (a Steel Dragon song in the movie, but it is actually a song by Steelheart, whose lead vocalist Miljenko Matijevic provides Cole's singing voice for the film).
