When one of the guests at the Fireside Inn is murdered, Max becomes a person of interest because the dead guest had complaints about the inn and was threatening to go public. The police also have discovered that the victim was killed by a left-handed assailant,and they think Max is probably the killer because he is starring in a play entitled The Left-Handed Man. Even though Max tries to convince them that he is actually strongly right-handed, the police chief is determined to prove Max to be guilty, and the only way he can save himself is by discovering who is the real Left-handed Man.
