Callan - Season 1 (1967)

Injured when out in the field, Callan must undergo a complete medical check-up. Bur what happens if someone wants you 'out of the way' for a few days - and is prepared to go to any lengths to achieve that aim?

Ordered to dispose of a member of the aristocracy, Callan, working outside the protection of the agency ('should anything go wrong, we don't know you') finds his mission hampered by Lonely's reluctance to help him.

When Lonely is beaten up after robbing a supposedly empty flat, Callan investigates on his behalf and discovers a link to a man named Pollock (Jon Laurimore), an enemy operative with whom he has had past dealings and who is currently under the Section's protection. After spotting Toby Meres leaving a safe house in which Pollock's girlfriend is holed up, Callan bluffs his way in and gets the operation details from her, then drops in to Section HQ to warn Hunter to keep his boys away from Lonely. Unfortunately for just about everyone, Meres has already paid him a visit.
