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.

Mayday 3DNA

Gao-bing works in a bakery in a small town. The owner, Mr Chiu, is so into his Rock 'n 'Roll band, and the apprentice Di doesn't seem enthusiastic about learning baking at all. The business of the bakery is getting down and Gao-bing doesn't know what to do with the situation. All he can do is work harder and makes more bread. Ping, the daughter of Mr Chiu, grew up together with Gao-bing and is Gao-bing's girlfriend. She often complains that Gao-bing only follows the traditions and doesn't take any dramatic actions to save the bakery. In order to develop revolutionary new flavors, Ping takes baking courses in the city where she meets Bread. Bread, born in America, is charming and humorous. He falls for Ping at the very first sight. Even though Ping is with Gao-bing, she finds Bread's bread has a special magic. She thinks Bread might be the one that saves the bakery
