A weekend trip to Fire Island at the end of the summer season brings three couples together at different phases of their relationships. Alex and Jackie are long-term girlfriends currently going through a dry spell. Alex’s sister Liz is there with her new boyfriend Dougie, in the sex-crazed honeymoon phase of their relationship. James and Spencer recently moved in together, but Spencer’s acceptance to a prestigious education program in Chicago puts a wrinkle in their plans. Bike riding lessons, a rainbow dildo, and lots of alcohol all force the couples to reexamine their life choices.
