Hallie Parker and Annie James are identical twins separated at a young age because of their parents' divorce. Unknowingly to their parents, the girls are sent to the same summer camp where they meet, discover the truth about themselves, and then plot with each other to switch places.

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.
