A village in the interior of Portugal is preparing the best village festival ever, in the year that marks the centenary of its greatest benefactor. Everyone does their best in organizing the party always with something in mind: the inheritance of the elderly woman.

Edward, a young expat gay man, finds himself caged in a glass box, after being abducted by the least person he could ever imagine: his own sister Helen. In order to be freed, he will need to be able to trick Helen, a deeply disturbed yet cunning woman, willing to go to great lengths to cure the young man from his birth nature.
