Is Jerry Helper (Jerry Paris) -- dentist, neighbor, best friend, loyal husband, and devoted father -- having an affair? That's the conclusion arrived at by Rob (Dick Van Dyke) and Laura (Mary Tyler Moore) when they spot Jerry at a restaurant, sitting at a table with a beautiful blonde who is decidedly not his wife Millie (Ann Morgan Guilbert). Once the comic byplay wherein Rob and Laura try to avoid being spotted themselves by Jerry is over, two problems remain: how can they learn the truth about the situation, and what can they possibly say to Millie?
