Past worlds can inform the present. In 1940, Antifa is Norway.

On the shore of Oslo Fjord, teenagers Kristian Thorsen and Helene Berg watch in shock and horror as their world is upended by a Nazi invasion.

Driven apart by tragic events, Helene and Kristian take different paths to joining the Resistance, but fate soon swirls them back together. Like many who rebel against the invasion, they must become spies and secret agents on the fly, making big mistakes along the way. Yet along this tortuous path, they are surprised by moments of grace.

When Helene manages to steal secret Nazi plans for precision bombing of England, Kristian launches a life-or-death effort to get that crucial intelligence across the North Sea and into Allied hands. He’ll try anything to defeat the fascist invaders—and to win Helene's heart.
