When the OC ladies travel to Jamaica on a girls' trip, the overwhelming heat gets to all of them. Emily and Gina confide in Tamra about Shannon's standoffishness. Meanwhile, Shannon laughs it up in a salt scrub with Vicki and Kelly. Shannon gets distracted by her own news from home, while Gina shares an emotional moment with the ladies. After some fun and games on bamboo rafts and rope swings, tension erupts between Shannon and Tamra.

Shannon continues to isolates herself from the rest of the ladies, who continue their trip with a day of adventure with a comical climb up a gorgeous waterfall. Later, Vicki coaxes Shannon to rejoin the group for a beachside dinner, where Shannon makes amends with only a few of the women at the table. An unexpected phone call makes Emily emotional.
