Time travelers, called "Faeries", are forbidden within the Kingdom of Spiders. Time marshals hunt down and kill anyone suspected of time travel. Amelie Peel was a solder in His Majesty's Royal Army, a spy working to uncover a secret Nazi experiment in time travel that threatens to turn the war in favor of the Axis. Peel discovers the time machine device in the form of a pocket watch and is transported to an alternate timeline where she meets herself in the form of a teenager called Whisper. Together, they try to bring Peel home. Between the Spider King, a sentient robot, his robotic minions, and the marshals, the duo are running out of time.
