Olly, a gallery invigilator decides to quietly add his own artistic input to the exhibits on show, challenging the authority of the artist/author, and exploring vandalism as an extreme attempt of (uncredited) artistic collaboration. A supposed visitor furthers the idea of impromptu collaboration going so far as cutting one of the canvases with a pen, in the style of artist Lucio Fontana. Olly confronts the mysterious man and is met with philosophical citations by Guillaume Apollinaire, Michel Foucault and Samuel Beckett.
