Jesse W. Haywood graduates from dental school in Philadelphia in 1870 and goes west 'to fight oral ignorance.' Meanwhile stagecoach robber Penelope 'Bad Penny' Cushing is offered a pardon if she will track down a ring of gun smugglers. She tricks the bungling Haywood into a fictitious marriage as a disguise, and he becomes the heroic 'Doc the Haywood' after he guns down 'Arnold the Kid' and performs other exploits with Penny's help (unbeknown to him or anyone else).—Doug Shafer
