Hotel night manager "Jonathan Pine" (played by Tom Hiddleston) is a former soldier, who fought in Iraq. Having witnessed too much during his time as a soldier he has withdrawn from life and all emotional relationships that it offers.

This is just the start of what becomes a very dangerous journey into the inner circle of one of the world's most ruthless arms dealers...
