Marina, a girl from a stunt team, passively assists to everyone's rush to choose the protagonist without whom the filming cannot begin. After weeks of nothing happening, the director, reviewing the footage on the screen, is struck by the photogenic photo of a young girl in an extras scene, which no one can identify. Marina doesn't want to reveal the secret to those on the set because, more pragmatically, her goal is different: admission to cybernetics!
