In an isolated and inaccessible Antarctic research station, winter has fallen on the South Pole, and the sun will soon disappear for the next six months. A small team, known as the Winterers, will remain at the Polaris VI Antarctic Research Station to continue their innovative research, a crucial part in the fight against climate change, under the command of renowned biologist Arthur Wilde. But when spring comes, summer commander Johan Berg returns to the station only to find the entire team are either dead or missing. A killer is on the loose, and Annika, Johan's wife, is missing. If he wants to find her alive, he will have to trust Maggie, the young doctor who is profoundly shaken and apparently the sole survivor from the group… or, is there someone else?

Based on Jake Adelstein's non-fiction first-hand account of the Tokyo Metropolitan Police beat. The drama captures Adelstein's daily descent into the neon-soaked underbelly of Tokyo, where nothing and no one is truly what or who they seem.
