A group of childhood friends, now in their thirties, reunite at Camp Tamakwa. Only a few of the original campers show up, but they still have a good time reminiscing. The people share experiences and grow while at the camp. They are dismayed to discover that the camp's owner, Unca Lou, is going to close the camp down.
Unfortunately the movie Indian Summer is not yet available on HBO Max.
