Three characters are plunged into a maelstrom of deceit. Barbara is a beautiful but psychologically unstable young woman that her husband tries to control. Damian, a convict with a murky past, dares not leave his prison for fear of seeing her again. Luis, the loving father of a sick little girl whose last dream he wants to fulfill, becomes a blackmailer, unaware of the dangers he risks.

After Diamond Flash in 2011, still unreleased in our parts, director-scriptwriter-illustrator Carlos Vermut, with Magical Girl, signs a twisted manipulative thriller crossed by occasional surrealistic visions, influenced by horror cinema as well as comic books and mangas. A former collaborator of Álex de la Iglesia, he reveals a mastery that his next feature film Quién te cantará (2018), will confirm. Barbara Lennie, seen in Rodrigo Sorogoyen's El Reino or Asghar Farhadi's Everybody Knows, plays one of the most striking female characters in contemporary genre cinema, at the same time a venomous seductress and a victim of her condition.
