Wolf Call (1939)

Playboy Michael "Mike" Vance Jr. is night-clubbing in New York City with Natalie. Natalie is shallow; Mike doesn't care. Mike and Natalie join a scavenger hunt and break-in a pet shop to get something they require for the treasure-hunt prize. While there, Mike frees Smokey, a police dog, who follows Mike home. The next day, Mike's father, disgusted with Mike's spoiled and care-free lifestyle and hangovers, sends him to the Vance Canadian Radium Mine to report back whether or not the mine is worth keeping. Mike takes Smoky with him. In Canada, Mike meets a priest, Father Devlin and Grogan, an Irish mine worker, and when Mike gets into a fight with "Bull," the impressed Grogan and Father Devlin befriend him. Mike meets with Carson, the mine superintendent, who tells Mike that the mine is losing money and should be sold to Radium Syndicate Ltd., Inc., because the cost of shipping radium is too high for a single owner. But Mike also meets Indian maiden Towana, who begs him not to sell the mine and introduces him to her father, Dr. McTavish, who is perfecting a new process of reducing radium which will make the cost of shipping it negligible. Carson declares that the McTavish process is no good, and then informs Mike Sr. that his son only staying in Canada because of his affair with Towana. The down-hearted Mike Sr. decides to sell the mine. Mike has to find a way to keep his father from making a mistake.
