Myth of a City(1985)

It is a school bus driver's last day at work. On a whim, he drives off to the seashore with the school's cook, a young teacher, and a busload of children. Facing an unhappy retirement, he seeks one great moment of happiness, which he finds on the road with the children. They encounter an aboriginal family, who invite them in for a feast, and then some young motorcycle riders, with whom they camp by the sea.
