It's 2014, and Amy Daughters is a 46-year old stay-at-home mom living in Dayton, Ohio. She returns to her hometown of Houston over the Thanksgiving holiday to discuss her parents’ estate and finds herself hurled back in time. 

Suddenly, it’s 1978, and she is forced to spend 36 hours in her childhood home with her nuclear family, including her 10-year old self. Over the next day and a half, she reconsiders every feeling she’s ever had, discusses current events with dead people, gets over-served at a party with her parents’ friends, and is treated to lunch at the Bonanza Sirloin Pit. 

Besides noticing that everyone is smoking cigarettes, she’s still jealous of her sister, and there is a serious lack of tampons in the house. Amy also begins to appreciate that memories are malleable, wholly dependent on who is doing the remembering. 

In viewing her parents as peers and her siblings as detached children, she redefines her difficult relationships with her family members and, ultimately, realizes that her life story matters and is profoundly significant not so much to everyone else, perhaps, but certainly to her. 

Amy’s guide said her trip back in time wouldn’t change anything in the future, but by the time her 36 hours are up, she’s convinced that she’ll never be the same again.
