José Farias, El Kiku, is a second-rate bullfighter who lives in Cádiz (deep south of Spain). Or rather, he was. Was, because someone has finished him off. And this, precisely, is the challenge: to find out who the culprit was by following a series of clues which have to be uncovered and analysed. A lot of suspects, a lot of humour and a lot of cinematographic clichés are used to explain, through the game, the close relationship that Mahou has with the Spanish cinema and, in this particular instance, with film noir.
