Biopic about Father Damian and his life and work on the island of Molokai.

Being a tramp is not always a disadvantage. For example when there is a masquerade ball. Indeed wearing flea-ridden rags might just mean having donned a costume. This is what happens to two resourceful Brussels bums, La Cloche and Picolard, who manage to gain entry in a fancy-dress ball. Once there, La Cloche is mistaken by an oriental prince for a respected doctor. His mission will be to give care to a music-hall diva. Even more exciting, he is asked to vaccinate a whole troupe of showgirls. Trouble guaranteed.

Kaatje, the daughter of the miller Schoonejans, and Jef, a little shepherd, who live near Delft, are happy together. In a floral parade, the carriage the two children have decorated with tulips wins the first prize. The next day, during a thunderstorm, lightning destroys the mill and kills Schoonejans. A life of misery starts for his widow and daughter. Remembering how the theatre manager Boolmans had applauded the dancing of Kaatje and Jef at the floral parade, the widow takes her daughter to Amsterdam, where Boolmans engages Kaatje. The years pass, and Kate has become a famous dancer.
