The film starts with a travelling kabuki troupe arriving by train at a provincial seaside town.

Kihachi and his son, Shinkichi, spend a fruitful afternoon fishing for dace in a nearby river.

Kihachi becomes enraged, warns Otaka never to come and harass the mother and son again, and breaks off his relationship with her.

To get back at Otsune and Kihachi, Otaka suggests to Otoki to try to seduce Shinkichi and offers her some money.

Otoki waits for Shinkichi at a tree by the road one day and offers to meet after her performance at the same place.
