A baby, found strapped to a donkey in the North Carolina mountains where her father drowned, is called Twilight and raised by the Anwells. At sixteen, Twilight, in love with her foster brother Jim, who runs the family's lumber business, grows jealous when Elise Charmant, vacationing with her father, a brain specialist, monopolizes Jim at the Fireman's Ball. After Twilight rings the fire alarm to stop the flirtation, she learns that Jim loves her. After the French Canadian lumberman Jules is caught robbing Jim's safe, he slips out of one handcuff and escapes. After he attacks Twilight and falls over a cliff, she becomes deranged thinking that he died. Although Dr. Charmant cannot help her, Twilight recovers when Jules returns after setting the woods on fire. When he attacks her, she shoots him in the leg, but he then handcuffs her to him so that she cannot leave him to die. After Jim carries them until he is exhausted, Twilight drags Jules and Jim to safety.—AFI
