When he is informed that Lime died a week previously in a car accident, Martins is intrigued by inconsistencies in the accounts of the death and decides that he can't leave the city without investigating matters further. As a consequence, he finds himself drawn into a web of intrigue and searching for the elusive 'third man' who was at the scene of Lime's death. When the head of the local military police, Major Calloway (Trevor Howard), informs him that Lime was involved in black market drug distribution, the plot thickens even further..
