If My Country Should Call is a 1916 silent drama film directed by Joe De Grasse and starring Lon Chaney, Jack Nelson and Dorothy Phillips.

But when she learns her son Donald is planning to enlist in the armed forces to fight the Mexican army down at the border, she decides she has to take matters into her own hands.

Margaret steals a small bottle of a heart depressant from the medical bag of Dr. George Ardrath (Lon Chaney) while he leaves it unattended.

She begins slipping very small doses of the medication into her son's drinks, which causes him to develop a slight heart murmur, so that he will not be able to qualify to join the army as he had planned.
