Nina and Maurice, a married couple who give each other one night off from fidelity, the titular "hall pass." Their lives quickly turn upside down as the one night of pleasure becomes a tool of deception.
Lauren Thomas is turning 40 and no one is more excited than her. She is married to Andrew, an amazing husband, a true provider and father. Andrew's brother, Franklin, is in a wheelchair due to a military attack. His wife, Mahogany, is currently pregnant with their first child. The two couples, along with three other couples and a few friends, are celebrating Lauren's birthday during the holidays since she is a Christmas baby. However, once the other women grow tired of Lauren bragging about her success, even though she is a stay-at-home wife, attitudes and snide comments take control. Over the course of the evening, things escalate and the entire cast gradually gets involved in the free-for-all until everything hits the proverbial fan.
