February 1939. Europe teeters on the brink of war. In New York City, twenty-two thousand cheering Nazi supporters pack Madison Square Gardens for a raucous, hate-filled rally.
In a Hell's Kitchen bar, Charles Mossman is reeling from the loss of his job and the demise of his marriage when a group draped in Nazi flags barges in.
Drunk, Charlie takes a swing at one with tragic results and a torrent of unintended consequences follow.
Two years later, Charles's estranged wife and six-year-old daughter, Emma, now live in a quiet brownstone in the German-speaking New York City neighbourhood of Yorkville, where support for Hilter is open.
Charles, just out of prison, struggles to put his life back together, while across the hall from his family, a kindly Swiss couple, Trudi and Willi Bauer, have taken a liking to Emma. But Charles begins to suspect that they might not be who they say they are.
