1959: Priscilla has grown up a ward of the nuns of Saint Catherine’s Academy, and she’s desperately seeking a divine purpose in life — and reeling from her feelings for another girl. Scrappy, genderqueer Sky has been sent to Saint Catherine’s by parents trying to literally straighten them out. When Priscilla thwarts Sky’s attempt to escape the Academy, the two accidentally awaken the ghost of a student who died on campus decades prior. Attempting to set her to rest and solve the mystery of her death, they uncover secrets about the school that shake Priscilla’s faith — and form an unexpected connection.
