A group of freshly graduated high school seniors are getting ready for a fun filled summer. After deciding to rent a beach house together for a week, things take a turn when a thunderstorm rolls in on the day that everyone is suppose to arrive, Muse A and B are the first to show up, making it just in time. The weather gets worse, causing roads to close and the rest of the group aren’t able to make it until the storm clears up.
They spend the weekend exploring the house and woods, cooking meals together, toasting marshmallows and getting up to all kinds of mischief. Eventually, a spark is ignited and they give in to the attraction between them the night before everyone else arrives.
But things become complicated when the rest of the group arrives, including Muse B’s boyfriend.
