Eight married college friends plus one other non-friend (all of whom have achieved middle to upper class economic status) go to Colorado for their annual week-long reunion, but the mood shifts when one couple's infidelity comes to light. As secrets are revealed, each couple begins to question their own relationship.

Four couples reunite for their annual vacation in order to socialize and to spend time analyzing their marriages. Their intimate week in the Bahamas is disrupted by the arrival of an ex-husband determined to win back his recently remarried wife.

The couples reunite in celebration as Marcus and Angela's daughter prepares to tie the knot. After being apart for quite some time, they learn quickly that as much as things change, they stay the same. Realizing their children have grown up to be so much like them, they reflect on the examples they've set and ask themselves that age-old question, why did they get married… again?
