In Alice Munro's "The Found Boat," what is the plot?

Like many of Munro’s stories, "The Found Boat" is set in
her imaginary small town of Jubilee, which is visualized as being in western Ontario,
near her own home town of Wingham. The story’s plot may be seen as the conflicts or
contrasts that young people experience at their time of growing sexuality. The "Truth or
Dare" game, for example, permits the young people to objectivize their private sexual
wishes in a mixed friendly setting. Similarly, the discovery and repair of the boat
offers the chance for companionship under the guise of cooperative effort. The high
point of the sexual by-play is the collective decision to strip and run to the river,
along with Clayton’s ejection of water from his mouth onto Eva’s breasts. At the story’s
end, it seems that the girls will try to resume their lives as they were before,
although their giggling suggests both their heightened emotions and their realization
that they are moving toward adulthood.
