A "perfect" group camping trip, obsessively organized by Kathryn McSorley-Jodell in honor of her adoring husband Walt's 45th birthday, is threatened by tension between Kathryn and her estranged best friend, Nina-Joy, the unexpected addition of a pissed-off goth teen and the chaotic arrival of Miguel, who is smack dab in the middle of a breakdown and toting his new girlfriend, Jandice, a woman of many talents who rubs Kathryn the wrong way.

After her son, Orvis, gets roughed up in a game of flag football, Kathryn rushes him to the nearest hospital, flipping out about his health and the danger that Miguel's girlfriend, Jandice, poses to the weekend. As Kathryn and Walt attend to Orvis, the others hit a local bar, where a racially charged remark to Nina-Joy awakens George's rage. Elsewhere, Miguel and Jandice create real issues for a prissy shop owner.

When the guys go on a fishing trip, Walt opens up about his dead-in-the-water sex life. Jandice encourages Carleen to loosen up and embrace her female strength. Kathryn's attempt to mend things with Nina-Joy is overshadowed by a big announcement. Miguel and Jandice's first misunderstanding gets serious fast.

A late-night pill swap leads a buzzed Kathryn to crash a neighboring campsite, where she runs into Nina-Joy, Carleen and some chic old friends. Unsettled by a revelation from Miguel, Jandice ends up sharing a beer with a forbidden friend.

With her plans turned upside down, Kathryn decides to cede control during a trip to the grocery store. There, Carleen starts to unravel, while a fed-up Sol vents. Nina-Joy and George explore the state of their relationship. Miguel tries to get back on Jandice's good side, but pays a price.

When Carleen goes missing, Kathryn's hunt for her sister finds her partnered with an eager Jandice, who wants to start fresh. Meanwhile, Walt tries on the role of unofficial deputy park ranger after coming to Harry for help.

With Walt's birthday party on the verge of collapse, Kathryn takes Jandice up on her wild suggestion. In the midst of the revelry, Nina-Joy is confronted by her past and makes up her mind about her future with George. Carleen returns to camp and doesn't like what she finds.

Tensions between Kathryn and Jandice boil over as Walt's birthday party winds down. George finds clarity in his relationship with Nina-Joy. Carleen laments growing older. Miguel has an awkward sexual encounter. Unexpected changes abound.
