　　The boys are rehearsing a dance for their traditional initiation ceremony into adulthood; their teacher instructs them. A girl observes the scene but is not allowed to join in. When one of the boys chases after a strange bird, she follows him without knowing why. One day, the boy will no longer be able to see the bird either.
