Ichiro Seike (Sho Sakurai) is a popular, 43 year old politician. He has gained popularity for his impressive smile and liberal speech and behavior. He is expected to be a future prime minster candidate. He has a secretary, Toshiya Suzuki (Tetsuji Tamayama), who carefully works to guide him to the prime minister position. They look like a perfect match as a politician and his secretary, but Reporter Kanae Michiura (Asami Mizukawa) feels something is off about the relationship of these two. She begins to investigate their past and notices the mysterious deaths that have followed Ichiro Seike during his rise in politics. Her own father's death, who was also a reporter, is somehow connected to the politician's past.
The Ministry of Time, a newly established government department, is gathering ‘expats’ from across history in an experiment to test the viability of time-travel. Commander Graham Gore (an officer on Sir John Franklin's doomed 1845 Arctic expedition) is one such figure rescued from certain death – alongside an army captain from the fields of the Somme, a plague victim from the 1600s, a widow from revolutionary France, and a soldier from the seventeenth century.
