The film's plot centers on rival lion dance troupes in Singapore -- a liberal-looking faction of a traditional troupe, Tiger Crane (led by Wang Wei Liang), breaks away from it to form a new one called Storm Riders (led by Tosh Zhang), which advocates a new style of lion dance with more modern influences of hip hop dance and more flashy acrobatics. Meanwhile, the male stars of the show clash with a third rival troupe called Black Hawk, competing in wushu, love triangles and of course, lion dance. Five of the well-loved Ah Boys To Men cast headline the film, joined by 23 unknowns.
