Nine months into motherhood, Elle is struggling. She's battling being sidelined at work, fighting to feel at home in her post-baby body and feeling pressure to be intimate with her adoring husband, Dom.

Elle turns to her charismatic new colleague, Gabriel, to get through the day and red wine to soothe her at night. For a while, the distractions work until one night she wakes up bleary-eyed in a hotel room next to a man who's not her husband. A dead man who's not her husband. Elle realizes Dom is the only person who can help her escape the hotel room with her future intact.
