April Poole (Davies), a young writer in love with publisher Kerry Sarle (Tearle), visits the office of Mr. Sarle and his partner Ronald Kenna (Frank) and reads her latest story to them. She has made Sarle the hero, Kenna the villain, and herself the heroine. In the story, April changes places with Lady Diana Mannister (Marshall), who is being sent to South Africa to separate her from her lover, a young artist. A famous diamond that Lady Diana is to deliver at the end of her journey is given to April. Thieves trail her during her journey. With efforts by Kenna to steal the diamond prevented by the intervention of Sarle, the story comes to a close.
