Grace Darmond, who had made quite a splash in the 1921 (and still extant) serial The Hope Diamond Mystery, returned to the Saturday matinees as Marjorie Stanton, the treasure-hunting damsel-in-distress of A Dangerous Adventure, produced in 15 chapters and directed by two of the Warner Brothers, Sam and Jack L. Warner. Marjorie and her sister Edith (Derelys Perdue) accompany their uncle (Jack Richardson) on a treasure hunt to Darkest Africa, where the latter fiendishly attempts to sell Marjorie to Ubanga (Rex de Roselli), the local High Priest. Happily, also along for the ride is handsome MacDonald Hayden (Philo McCullough), a wild game hunter who rescues both girls from several fates worse than death.
