After the "event," 38-year-old Alice finds herself completely alone-cruelly separated from her children and left with only vivid, haunting dreams of life as it was. Fueled by her sharp survival instincts and sheer resilience, Alice moves through each day like the one before-until she discovers she's not as alone as she thought. Alice's need for human contact helps her overcome her apprehension about Ben, the only survivor she's encountered for months. As the two are drawn closer together by their shared desire for companionship, their individual pasts begin to reveal that everyone is not exactly who they seem.
