Obsessively organized L.A. mom Kathryn plans a camping trip in honor of her husband Walt's 45th birthday, hoping the get-together with old friends lessens tension in their not-so-happy marriage. As they arrive at the underwhelming Brown Bear Lake site with Kathryn's meek sister, her holier-than-thou ex-best friend, and a free-spirited tagalong, the supposed delightful, back-to-nature camping trip quickly becomes a weekend of tested relationships, heightened emotions, and memories everyone would rather forget. Lena Dunham ("Girls") is among the series' writers and executive producers.
