Saskia Brown feels like an outsider at her new school being biracial in a population of mostly white students. One day she encounters a vial of liquid mercury, touches an old style of photograph and makes a discovery. She's able to visit the man in the portrait although only in her dreams. Under her guidance, other girls in her class steal portraits of men from the photo collection too and try the experiment for themselves. At first, the Mercury Boys Club is a diversion from their everyday lives, but it's not long before jealousy, violence and secrets threaten everything the girls have.
