A group of miserable, middle-aged men decide to reunite their old band, and recruits their late-singer's son to take over on vocals in this gently nostalgic comedy from Korea. Back in college, Active Volcano was the hardest-rocking band on campus. Twenty years later, former guitarist Ki-young (Jung Jin-young) is on a short leash at home, bassist Sung-wook (Kim Yun-seok) breaks his back to send his sons to a decent school, and drummer Hyuk-soo (Kim Sang-ho) hawks used cars to support his wife and children in Canada. When their former lead singer, Sang-woo, dies unexpectedly, depressed Ki-young reforms the band with Sang-woo's son (Jang Keun-suk) on lead vocals. Now, with a little luck, Active Volcano will rise from the ashes and achieve world domination!
