As a record-breaking heat wave descends upon Camp Little Otter, everyone tries their best to keep cool. Buzz, who is celebrating his 16th birthday, begins planning "the greatest party Little Otter has ever seen". Sarah's trip over to Camp Ridgefield to borrow a much-needed generator gets interesting when she runs into her secret crush Miguel Santos. When Buzz spies Kip kissing Chloe, he is hurt that his friend didn't share the news and retaliates by starting up a rousing game of "Truth or Dare", that is meant to humiliate Kip into confessing to everyone. Meanwhile, Mack gets an unwelcome surprise when her ex-husband gives Buzz the night vision goggles she had planned to give him for his birthday. Cole comes to her aid to help re-think a perfect birthday gift and the two spend a carefree afternoon in town.
Off the grid and miles from civilization, Little Otter Family Camp has summer fun for everyone.
Mackenzie Granger is the camp owner and director. Still reeling from her recent divorce, Mackenzie is ready for a fresh start. She is running things on her own for the first time and scrambling to keep the cash-strapped Little Otter from going under. She considers a buyout offer from Roger Shepard, the arrogant but sexy owner of the upscale camp across the lake.
Despite her better judgment, their love-hate relationship quickly escalates. Meanwhile, she begins to realize that her charming but much younger handyman, Cole, might be interested in more than just a professional relationship.
In the midst of all this, Mackenzie is struggling to be a single parent to her brash and exuberant oddball of a son, Buzz, who is a counselor-in-training at Little Otter this year.
