After the first season meets by the viewers, season 2 completes the struggles that section 20, a group of secret agents who do their best in order to save the world and face terrorists, such as detective Michael Stonbridge, who struggles against stopping the bomb that put in a hotel in Delhi by terrorists.
It's all terribly unfeasible, but Tim Pigott-Smith leads a good support cast and, at least in this opening episode, there's little sex (there's usually loads) to distract from the shoot-'em-up action.
A viewer can really feel it as having an stand-apart identity. Which is very important for an action series like this. Bullet storms and exotic locales can easily blend together and mean nothing if done poorly.
