Mr.
van Welderen, a former military officer forced into early retirement following a debilitating horse riding accident, lies on his couch in the living room. The injury left him invalid, in constant pain, and unable to walk more than a few steps. This misfortune brought severe financial strain to the household, as he and his resilient, cheerful wife have to raise five children—Mathea, Margerita, Jan, Bets, and Nico—on a limited pension. To alleviate their financial burdens, Mr. van Welderen attempts to earn extra income through translating and writing military sketches, though his frequent pain often disrupts his work.
The eldest daughter, nineteen-year-old Mathea (Thea), has dedicated herself to studying intensely to become a teacher so she can earn money and relieve her father's financial worries. Having already passed her lower education exam in April, she spent the subsequent five months preparing for her English certification. Today is the day of her examination, and Mr. van Welderen is overcome with restless anxiety while waiting for her return, unable to read or focus on any task. His wife attempts to soothe his nerves and maintain an optimistic outlook, even as he expresses deep guilt over his inability to provide for the family and fund young Nico's school tuition.
As the afternoon progresses, thirteen-year-old Jan and young Nico return from playing outside. Jan takes his place at the window to watch for his sisters. Suddenly, Jan spots two figures approaching in the distance and excitedly announces that Thea is running toward the house while waving a white paper, signaling her success. Mrs. van Welderen rushes to open the door, greeting Thea and her sixteen-year-old sister, Margerita (Ita), who is dancing with joy.
Thea bursts into the living room and shares an emotional, tearful embrace with her relieved father. The entire family gathers around to celebrate her achievement. Nico presents her with a bouquet of roses, and Thea enthusiastically details how smoothly the examination went once her initial nervousness subsided. To commemorate the milestone, Mrs. van Welderen brings in a tray of eggnog and biscuits. The family toasts to Thea’s success amid cheers and laughter. Shortly after the celebration begins, ten-year-old Bets returns home from school, eagerly anticipating the good news and the treat. After congratulating her sister, Bets contentedly joins the gathering, expressing her relief that she does not have to retract the proud announcements she had already made to her schoolmates.
