Crime drama told in three sections, each following a different murder. In the first story, 'The Picture', tour guide Jarvis (Hugh Pryse) is faced with bizarre going-ons at the museum he works in. One day, he follows a stranger (Alan Badel) into a mysterious painting and suffers the consequences of the dangerous world beyond the frame. The second tale, 'You Killed Elizabeth', sees friends George (Emrys Jones) and Edgar (John Gregson) fall for the same woman - Elizabeth (Elizabeth Sellars). How will their friendship be affected when Elizabeth is found dead? The final segment, 'Lord Mountdrago', stars Orson Welles as the title character, a secretary of state for foreign affairs who abuses his authority to bring down his political adversary, Owen (Badel). But when Owen haunts Mountdrago's dreams, the Lord seeks help from his psychiatrist (Andre Morrell).
