Aristocratic millionaire Peter Hedley Lamar Jr. (Buster Keaton) is entranced by army nurse Dorothy Appleby but her cohort Elsie Ames lets Lamar know that Dorothy is only interested in men in uniform. Lamar enlists to be near Dorothy, but Elsie tries to woo Lamar by singing a silly song to him (and Buster sings and dances!). Still interested in Dorothy, Lamar wounds himself to get under the care of Dorothy. Elsie is still after him, but Dorothy finally comes around after Lamar saves her life.<ref name="p181"></ref>
