Madrid, 1962. More than twenty years after the civil war has finished, a communist comes back to Spain to kill a traitor.

Captain Darman is a communist party hitman now living peacefully in exile in England where he runs a bookshop in Brighton. That is until a visitor gives him a coded message summoning him back to Spain where he's instructed to execute a traitor. As he prepares for the hit he starts to doubt the guilt of his target as it bears similarities to a previous hit which he now thinks was innocent.—tonyman5
