Mouna Rudo was born and raised among the Seediq people, an indigenous tribe in Taiwan, and as he grew to be a man he became a member of the Seediq Bale, a courageous band of native warriors. However, Rudo's way of life is threatened under the yoke of occupying forces from Japan, who took over the nation in 1895. As Rudo sees the traditions and honor of his people stripped away, he realizes the time has come to fight back, and in 1930 he brings together a group of former Seediq Bale soldiers, many of whom have been reduced to infighting, and molds them into a revolutionary army. Rudo and his comrades make their stand when they confront Japanese occupation troops at a youth athletic event, leading to a violent confrontation between the Seediq forces and their oppressors. Warriors of the Rainbow: Seediq Bale - Part 1: The Sun Flag is Part one of the two-part, four-hour Taiwanese edition of the film Warriors of the Rainbow.
