From the press release:
A husband and wife, each embroiled in a secret, extramarital affair, are sent reeling when they suddenly fall for the least likely person imaginable – one another – in this scalpel sharp and deliciously grown-up comedy that enters the fray where family, love and attraction become madly tangled.
Michael (Tony and Pulitzer Prize Award winner Tracy Letts) and Mary (three-time Oscar® nominee Debra Winger) are long past passion, never mind patience, after decades of turmoil and tedium in their marriage. Each is now contentedly distracted by a lover on the side. And each fully intends to call it quits on the other after one last family get-together with their collegiate son (Tyler Ross). Michael has his hands full with a fiery ballet teacher (Melora Walters) while Mary is canoodling with a playful novelist (Aidan Gillen) – and both have grown bemusingly accustomed to claiming “late nights at the office.” But when the dried-up spark between Michael and Mary unexpectedly, indeed feverishly, reignites, it sends their plans into chaos, forcing them to navigate the hilarious new complications of having to “cheat” on their respective lovers. It all sets the stage for a collision of betrayals and agendas that builds to a truly unforgettable ending.
