Sonny Boy is a 2011 Dutch film directed by Maria Peters, after the book by Annejet van der Zijl, based on a true story about interracial love during the WW2.

He moves to lodgings in The Hague with Rika van der Lans, who went to live separated from her deeply religious husband Willem, after she discovered him cheating with the maid Jans.

Waldemar returns, and when Willem visits Rika to tell her about a job opening in Indonesia, he asks her to come along.

Rika and Waldemar roam the streets with Waldy, when they meet an older Jewish man, Sam, who rents them a room.

At the request of a young resistance fighter, Kees Chardon, whom she met through the help of a clergyman, Rika starts hiding people in her house.

At first Waldy is not aware about the individuals hiding there, but after witnessing Sam’s deportation and a street fight, Rika is visited by a collaborating official.

The farmer refuses Waldy’s rings and explains everybody tries to make some money during wartime, also Rika and Waldemar were paid for the hiding.

In the end credits, it is revealed Rika had died that year in KZ Ravensbrück after an epidemic of dysentery.
