In the charming city of Brookline, Massachusetts, Charles and Annie Woodworth appear to have the perfect marriage. Seven years in, they have everything money can buy: success, security, and a carefully crafted image. According to their prenuptial agreement, Annie can do whatever she wants, as long as she never embarrasses her husband.

The problem? Annie has secrets.

So do Evelyn and Noah. Living sort of a double life hidden in plain sight, they've managed to keep their private world just that, private.

When the two couples' lives become intertwined, and someone suddenly disappears, secrets rise to the surface. The question is no longer who's lying, it's who will survive the truth.
