Callan 202 The Most Promising Girl of Her Year (15 Jan 1969) sample frame from video
Callan is a reluctant assassin working for a shadowy department of the British government that is responsible for the dirty jobs, such as the elimination of undesirables by whatever means is necessary. Callan's life is bleak, his only friend a smelly small-time crook known as Lonely. Continually at odds with his superior, who is known as Colonel Hunter no matter which individual currently holds the job, he is a liability because he cares about the effects of his work, even though he knows how to do little else. The Section has often tried to eliminate him itself, but always ends up either needing his expert services too much or being out-maneuvered by him.
In this episode, Callan must prove that a young biochemist is not passing secrets to the East.
