After her car breaks down in the
Arizona desert,
New York socialite Amanda Lawrence accepts a ride from Jonathan Dartland, a
mining engineer, and his friend Hugh Slater, a doctor with a penchant for
liquor. Invited to a party hosted by her wealthy mother at the resort where they are staying, "Dart" claims to dislike mothers, especially those of spoiled beautiful daughters, but he and Amanda fall in love and quickly marry. Amanda's mother is not pleased to hear that Dart's mother is an
Apache Indian princess, once married to a
Boston college professor, who has taken back her Apache name and never sees her son. Dart works in the mining community of Lodestone for Tyson Copper, where women are not welcome because of miners' superstitions, but wants to re-open the abandoned "
foxfire" shaft, where he hopes to find a legendary vein of gold. Amanda adjusts easily to the rustic living conditions of Lodestone, and to the meddling opinions of the wife of the mine superintendent Jim Mablett, but feels devalued when Dart apparently does not want children. When his attention is completely occupied trying to get the foxfire project going, she innocently spends time with Hugh, who makes no secret to others that he is still attracted to Amanda, causing gossip in town begun by the jealous Maria, Hugh's nurse. Dart is reticent about his background and ambitions. A pregnant Amanda opens a footlocker he mysteriously keeps locked, learning more about Dart's background. Dart resents the intrusion, believing she did so only out of bored amusement. Trying to win his trust, Amanda persuades the reluctant company owner, Mr. Tyson, to back Dart's foxfire project but this also backfires when Dart's pride is injured. She seeks out his mother, who explains her son's cultural attitudes, which include a belief that love is only temporary and that fathers do not acknowledge sons until they come of age and abandon their mothers. Dart has heard the rumors and misdirected by Maria, believes she is having a tryst with Hugh. When she returns, he is intoxicated and accuses her of being unfaithful. After she explains, he is contrite but they continue at cross purposes when she angrily rejects his drunken advances. Amanda falls during a dizzy spell and has a miscarriage. Dart, unaware she was pregnant, tries to see her in the hospital but accedes to Hugh's dissuasion not to. Hurt by Dart's adherence to the "old ways" and telling him that he has treated her "like a squaw," Amanda intends to return home with her mother. At the foxfire shaft, which legend has is on ground sacred to the Apaches, many of them refuse to continue working after one of them has a seizure. Dart goes into the shaft to overcome their superstitions. It collapses and injures his hands, but he also finds the vein of gold. Informed at the airport by Maria that he's been hurt, Amanda rushes back, where Dart admits that the mine collapse showed him that he needs her and is no longer afraid of love. At the mine a new "Foxfire Gold Company" sign is erected. ==Cast==
