　　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.
