"Indian Summer" starts out like one of those reunion movies where friends from long ago gather again, to settle old scores, sort out old romances, open old wounds, and make new beginnings. All of those rituals have been performed by the end of the film, but curiously enough, the movie isn't really about what happens. It's about how it feels. This is a story more interested in tone and mood than in big plot points.
The film takes place at Camp Tamakwa, on the wooded shores of an Ontario lake, where an aging camp director known to everyone as Uncle Lou (Alan Arkin) has invited some of his favorite campers to return for an autumn reunion before the camp is boarded up for good.
