Mild-mannered suburbanite Rob Clark is shocked when Eugene, an unlikely angel, tells him that he is going to have a baby. Rob and his wife, Cindy, have wanted a child, but they never expected Rob to be the one to get pregnant! Their family physician, Doc Mitchell, an old-fashioned doctor who'd rather be fishing, confirms the pregnancy, but Dr. Stern, a cynical psychologist, says everyone is nuts! Meanwhile, Rob and Cindy, who are trying to come to terms with the situation, are besieged by a parade of curiosity seekers, led by Dr. Stern, while Doc Mitchell comes under investigation by the medical association. By the time Eugene finally realizes he has made a mistake, everyone is actually disappointed - until another angel, Eugenia, makes a surprise announcement of her own.
