Harry defends a teacher who was fired for failing a student because of their conflicting ideas of evolution, while Ollie helps out an old girlfriend.

While Harry is on vacation, her trip takes a frustrating turn when the small town of Langford, Ohio impounds her Mercedes Benz for violating their "Buy American" law. Harry, with Oliver at her side, challenges the town's law and is pit against a young, homespun attorney and the engine behind the law, Langford's mayor, Franklin Chickory. Meanwhile, Adam represents the Chens, a Chinese family whose daughter was stolen because of China's one-child policy and adopted by American parents. With Cassie's help, Adam hopes to win custody for the Chens.
