I'll Say So / 1918

Hearing that the United States has just declared war on Germany, Bill Durham hurries to a recruiting station to enlist, but because he has flat feet, he is rejected. He falls in love with Barbara Knowles, whose guardian, August Myers, unknown to Barbara, is a German agent. When Bill learns that Myers plans to stir up trouble on the border of the United States and Mexico, he catches the train to New Mexico and routs out Myers' gang of bandits.
