Smashing Through

剧情简介

Dave Marco, a claim jumper, and his boss Earl Foster, a crooked investment broker, hire chemist Ralph Brandon to sign papers proclaiming the wealth of a certain mine. Foster then convinces Ralph's mother to invest all of her money in the mine, which actually is worthless. While she and her pretty daughter Holly are waiting in Foster's San Francisco office, they meet Jack Mason, whose rich mine has not yet earned him any profits, and the two young people fall in love. Inspecting her mine in Keno County, Mrs. Brandon learns that it is worthless, but when she confronts Foster, he threatens to have Ralph arrested for signing false documents unless Holly agrees to marry him. Meanwhile, Marco tries to jump Jack's claim but is prevented from doing so by Jack and a sheriff's posse. Foster weds Holly in an illegal ceremony, but Jack and Ralph overtake their train with the aid of a car and then a motorcycle. Finally, Ralph kills Foster, freeing Holly and her mother from his clutches.
