Ten years ago, June’s beloved husband, Josh, drowned on their honeymoon, and his body was never found. Now, a decade later, June is finally ready to move on. She owns a natural wine bar in Brooklyn and is engaged to a patient, supportive man named Kyle. But out of the blue, she sees Josh. Is this just a hallucination from the guilt June carries about finally moving on, or is it possible that he never died in the first place? Soon enough, she stumbles across a website for a winery in Napa, and the owner in the photo is identical to her dead husband. With her upcoming wedding looming, June secretly flies to Napa for answers. But she’s not prepared for all the secrets she’s about to unlock because everything she thought she knew about her first love is a lie.

Ambrosia Wellington receives in the mail an invitation to her 10-year reunion, along with an anonymous note that reads “We need to talk about what we did that night.” It seems that the secrets of Ambrosia’s past aren’t as buried as she’d believed. Amb can’t stop fixating on what she did or who she did it with: larger-than-life Sloane “Sully” Sullivan, her former best friend, who could make anyone do anything. At the reunion, Amb and Sully receive increasingly menacing messages, and it becomes clear that they’re being pursued by someone who wants more than just the truth of what happened that first semester. This person wants revenge for what they did and the damage they caused --- the extent of which Amb is only now fully understanding.
