When eight married college friends reunite for their annual retreat in the snowcapped mountains of Colorado, they come expecting fun and relaxation, but get a completely unexpected surprise. Career-driven Dianne and her supportive, but fed-up husband, Terry, are joined by popular psychologist and best-selling author Patricia and her architect husband Gavin, who share a secret tragedy that finally comes to light, while Angela and Marcus argue constantly, but remain in love. Also in attendance is their good friend Sheila, a sweet woman with a distorted self-image stemming from weight issues that are exacerbated by her emotionally abusive and philandering husband, Mike. Unlike any other year, this trip changes the dynamic of the group with two new additions: Sheila's supposed girlfriend, Trina, who is secretly sleeping with her husband; and Troy, an ex-Wall Street stockbroker who has put his career on hold to care for an ailing father.
