Waikiki Brothers is a band going nowhere. After another depressing gig, the saxophonist quits, leaving the three remaining members - lead singer and guitarist Sung Woo, keyboardist Jung Suk, and drummer Kang Soo, to continue on the road. The band ends up at Sung Woo's hometown, Suanbo, which was a popular hot spring resort in the '80s. The main resort now is the Waikiki Hotel, and their gig at the hotel nightclub starts well, until Jung Suk and Kang Soo start to play out their worst vices.
