Mayday Life Tour is linked by four distinct segments and the story is unveiled in “Yesterday’s Rumbling Fun”.

Billed as a "concept film" MAYDAY 3DNA combines play from the group's DNA concert tour in Taiwan, Hong Kong, Singapore and China 2010 and interweaves that with three fictional stories. The fictional sequences include a vignette about a Guangzhou father and daughter; another about a Taiwan taxi driver and passenger; and a third about a Shanghai delivery boy. All are affected by the lure of a Mayday gathering and the three separate stories intersect at one particular Mayday concert in Shanghai. Established in Taiwan in the late 1990s, Mayday has remained popular for over a decade by tuning into a Taiwan youth beat and pushing rock music in Greater China. Most songs are performed in Mandarin with some Taiwanese Hokkien tracks by band.
