Bodyguards

Stand Off (1x6)

Air date: May 29, 1997

Commander MacIntyre isn't particularly pleased when his old mentor, who defected to Russia several years ago, wants to come back to the UK to visit his daughter's grave. But his duty is clear. The problem is that the bodyguard unit soon finds evidence of a mole somewhere inside her Majesty's secret service, someone who desperately wants the defector dead.
