Liam Pace is the brother of Charlie Pace and co-founder of their one-hit-wonder rock band, Drive Shaft. Liam was a drug addict and his explosive relationship with his brother, Charlie, led to the band's demise. Now sober and living in Australia, Liam was the reason Charlie went to Sydney, hoping to talk his brother back into the band. Liam passed and Charlie set off for L.A. alone.
