Vince Vaughn explores the grey areas of romantic relationships in director Ron Howard's darkly comedic look at the various secrets in two couples' lives.
Best friends since college, Ronny (Vaughn) and Nick (Kevin James) run their own auto design company and have been invited to pitch to one of America's biggest car manufacturers.
Nick is stressing about the meeting when Ronny sees Nick's wife Geneva (Winona Ryder) kissing another man.
Upset and unsure what to do, Ronny can't hide his agitation from long-term girlfriend Beth (Jennifer Connelly), who immediately assumes that his gambling addiction has returned.
Misunderstandings ensue, including a misplaced intervention, and additional secrets are revealed, forcing both couples to find their way to the truth. With Channing Tatum and Queen Latifah.
