Set in 1965 New York City, Apartment 7A tells the story prior to the legendary horror classic Rosemary’s Baby, exploring what happened in the Bramford building before Rosemary moved in.
Ambitious young dancer Terry Gionoffrio (Julia Garner) dreams of fame and fortune in New York City, but after suffering a devastating injury, an older, wealthy couple (Dianne Wiest and Kevin McNally) welcomes her into their home in the luxury apartment building the Bramford. When a fellow resident and influential Broadway producer (Jim Sturgess) offers her another chance at fame, it seems that all her dreams are finally coming true. However, after an evening she can’t fully remember, disturbing circumstances soon have her second-guessing the sacrifices she’s willing to make for her career as she realizes that something evil is living not only in Apartment 7A, but in the Bramford itself.
