An excellent drama which focuses on a family drawn into a frightening, and very relevant, terrorist situation. A bit of a continuity blunder early on seems to have given some people a bit of a stick to beat this programme with but, embarrassing as it may have been, it has no real effect on the story. Tension builds nicely to a genuinely moving conclusion. The actors create a believable family dynamic which is far more effective for the telling of the story than having some maverick cop-type character or Strike Back style antics doing everything for them. Nice to see Archie Panjabi in a lead role in the UK too - long overdue.
