The Young Master

The school attended by Dragon (Chan) and his brother, Tiger (Wei Pei) is entered against a rival school in a Lion Dance competition. The school needs to win the prize money to remain open but their star performer, Tiger, is seemingly injured when he falls from a ladder, leaving his brother, Dragon, to take his place. During the competition, Dragon realizes that his brother feigned his accident in order to take part in the competition for the rival school.
