Spooks: The Greater Good

Harry Pearce (Peter Firth), the long-serving head of counter-terrorism at MI5, is in the middle of a handover when a terrorist slips out of custody. Then Harry himself goes missing, and Will Holloway (Kit Harington), the protégé he trained, is sent to find out why while an attack on London draws closer. Bharat Nalluri makes the case for loyalty to a mentor over loyalty to the service, and Will has to decide which one he will answer to.
