Twelve friends, six couples, and an affair that could ruin everything…

Six couples meet at the nursery school gates, and form an extraordinary friendship. The husbands and wives may be all different, but their children have given them a ticket into a friendship group that wouldn’t otherwise have existed.

Through the years they form a strong, reliable, consistent bond. They celebrate, commiserate, laugh, and grow older together.

There is no doubt that this group loves each other. Treasures its shared history.

But what happens when lines are crossed? An affair that happens within a close circle is especially devastating, testing loyalties to their limits.
