Desc: Heart Trouble: Directed by Harry Langdon, Arthur Ripley. With Harry Langdon, Doris Dawson, Lionel Belmore, Madge Hunt. Harry Van Housen, the son of German immigrants, desperately wants to enlist in the United States Army during World War I in order to prove to his sweetheart that he is a true-blue American. Every time Harry volunteers for service, he is turned down for unfitness: he is underweight, four inches too short, nearsighted, flat-footed, and suffering from dandruff. Unwittingly, he comes across a German base being used to shuttle supplies to submarines off the United States coast; all unknowingly, he manages to free an American officer, blow up the base, and round up the spies. Harry is given a hero's welcome by his hometown, but he misses it, being too busy courting his girl to care about civic honors.
