Truus' 1930 film "Susanne macht Ordnung" ("Susanne Cleans Up") proved very popular both in Germany and in America. For the first time, Truus got top billing for her part as Susanne Braun, a 17-year-old orphan attending a Swiss boarding school, where she's been living since she was little. She meets Robert, a young man on holiday from Berlin, and they fall in love. His questions about her family embarrass her - she believes that her mysterious father is still alive. Helped by another girl, she scrapes together enough money to set off to Berlin to look for him. As the film progresses she finds several possible fathers, and greets each one with "Hello, Papa!", causing huge confusion and breaking up his marriage. The film, a musical comedy, was reviewed by the New York Times in October 1931: "With the arrival at the Belmont of Truus von (sic) Aalten, as the stellar performer in "Susanne Macht Ordnung", those understanding German will have an opportunity of enjoying the work of an excellent young screen actress," the reviewer wrote, adding that Truus was "alert and interesting" in her role. "The banking concern of which Susanne's father is a member is in distress, and can be saved only through his marriage to the adipose sister of the firm's heaviest creditor. He is about to consent to the marriage, when Susanne's arrival causes great confusion. It seems impossible for her to ascertain who is her father and finally she gives up the investigation, refusing the protection of the man who really is her father. But all is not lost, for Robert, who has had his own troubles trying to find Susanne in Berlin, encounters her eventually and all is well."
