Chicago defense attorney Anne Talbot learns that her father, Hungarian immigrant Michael J. Laszlo, is in danger of having his U.S. citizenship revoked. The reasons are that he stands accused of war crimes. He insists that it is a case of mistaken identity. Against the advice of her former father-in-law, corporate attorney Harry Talbot, Anne resolves to defend her father in court. One of her reasons is how deeply her son, Mikey, loves and admires his grandfather.
