If there's one thing that brings in the viewers it's controversy, and this comedy about a British bomb disposal unit in Afghanistan has certainly caused it's fair share of that. Bluestone 42 shifts the focus away from the action on the front, choosing to deal with the friendships, the bonding and the banter between the soldiers in the unit. They're facing extreme danger, but they're only human after all. Tonight's episode sees the team facing a difficult roadside operation, while new padre Mary gets lusty captain Nick's attention. You'll recognize a few faces.
