There are secrets Chris (Jeb Stuart Adams) and Cathy (Kristy
Swanson) never knew about their parents. After their father dies, the
teenage siblings, along with their younger brother and sister, are sent
to live with their cruel grandmother, Olivia (Louise Fletcher). Olivia
is disgusted by the children - she knows their
mother (Victoria Tennant) and father were actually cousins - and locks
the brood in the attic. The kids then try to keep their spirits high in
spite of their bleak situation.
