When Saffi and Oliver sneak into their grandparents' attic, they uncover an antique pocket watch with incredible powers - it can transport them back through time! But when they accidentally activate the mysterious watch, it whisks them away from modern-day to World War 2-era London.
Now trapped in 1940s England, the siblings are horrified to witness firsthand the terrors of the Blitz and the hardships of life during wartime. Seeking help, they set out to find their grandfather, William, a brilliant but eccentric inventor. Can he help them solve the watch's secrets in time to send them back home?
But soon after connecting with young Grandpa William, he and his assistant Evelyn are kidnapped by sinister Nazi spies with their own plans for the pocket watch - and its ability to rewrite history to their evil aims.
To save their grandfather and the future itself, Saffi and Oliver must conquer their fears, solve coded puzzles spanning generations, and outwit ruthless villains. Failure could trap them in the past forever...and allow the Nazis to reshape time itself to their evil will.
