In pre-World War II Netherlands, a young man named Waldemar from Suriname crosses paths with Rika, a middle-aged Dutch woman, and love blossoms between them. Despite profound differences – one Black, the other white, with a 17-year age gap, and Rika already a mother of four from a previous relationship – their affection for each other runs deep. When Rika becomes pregnant with Waldemar's child, they make a bold choice to be together, fully aware of the sacrifices they'll need to make.
Their love story brings forth a son, Waldy, their own 'Sonny Boy.' However, the outbreak of World War II casts a dark shadow over their lives. In the face of the war's turmoil, they risk everything to shelter individuals in hiding, displaying extraordinary courage. Yet, these courageous actions come with significant and far-reaching consequences that will shape the course of their lives in profound ways.
