Charlotte (Katherine Waterson) and her mother Kit (Fiona Shaw) both live their own sets of lies. Upset in her marriage, Charlotte flees her ranch and husband in Alberta, Canada to stay with her mother in their family’s Park Avenue apartment. Secrets are bound to come out, such as: Why is Kit suffering from dizzy spells? Why did Charlotte’s parents smuggle masks out of China? Who is Johnny Johnson? How did Charlotte’s father die? Where have Charlotte and the doorman gone, and why are the walls shaking? Directed by Gaby Dellal, Park Avenue shows there’s more to the Upper East Side than class and glamour – there’s also family tension.
