Eight billionaires meet at a luxury resort to smoke cigars, tell tall tales, and pat each other's backs. Crashing the party is a group of four anarchists who are going to try each billionaire for crimes against the world and then execute them.
Ros is at the party as a guest, and when all hell breaks loose, she gives MI-5 a heads up as to what is happening. The anarchists take the billionaires and their family and support staff down to a bunker under the resort. Their plan is to kill everyone and blow up the building.
However, before they can do that, they have to drill holes into all the concrete pillars to attach the bombs. Anybody with half a brain should have thought to shut off the electricity to the bunker. Nobody can drill holes without electricity. Nobody can send video of trials to the internet without electricity. The website should have been shut down too.
On NCIS, Criminal Minds, and The FBI, turning off the power is usually at the top of the list. Inside a bunker, without windows, the bunker would have been pitch-black if the lights were off. It seemed like MI-5 enabled the anarchists to broadcast the trial, the killing, and the website. Drama is great, but it would be better if the story made sense, and MI-5 were a step ahead instead of two steps behind.
