Exemplifying Kipling's adage, a white man falls to pieces when he is in the South Seas.

New York police sergeant Jim Dark is determined that his daughter, Jenny, will be shielded from any knowledge of evil. Consequently, she lives in a dream world, imagining herself to be a descendant of Saint Jeanne d'Arc, but has a loyal friend in reporter Pep Mullins. Her school friend, Adele, also raised by overly protective parents, is ejected from her home when she becomes inebriated after spending an evening with a disreputable young man.
