Marios learns that he is HIV positive and is convinced that this situation arose either from his wife, whom he discovers has been having an affair, or his mistress. He gets his wife to have a blood test and she, too, is HIV positive. He is planning to get a divorce and marry his mistress when she reveals that she's been quite promiscuous and is HIV positive herself -- and doesn't want to marry him. Her way for bringing home to him the extent of her promiscuity is quite novel: she has him watch a slide show composed solely of pictures with her and her various holiday boyfriends. Since Marios was hoping to get free from his loveless marriage, this news doesn't please him much.
