Jonathan (Tom Hiddleston) was a soldier fighting on the front line in Iraq. After retiring, he came to a magnificent hotel and worked as a night manager. One day, Jonathan met a beautiful woman named Sophie (Aure Atika) in the hotel and fell in love with her at first sight. However, Sophie was the mistress of an arms smuggler. She secretly handed a confidential document involving Richard (Hugh Laurie), a British arms black market tycoon, to Jonathan and then died. After that, Jonathan came to work in a hotel in Zermatt, Switzerland, where he met British intelligence officer Angela (Olivia Colman), who threw an olive branch to Jonathan, hoping that he could help her investigate the arms trade and secret intelligence in the black market.
