What's behind Father Frank's bizarre behaviour? His housemaid played by Mary Wickes keeps a distance as he whispered something inappropriate to her. Sister Stevie sees him at a sleazy bar with a floozie, dancing away very closely. She's perplexed - but there must be a reasonable explanation to this bizarre behaviour. And the simple explanation is that Father has a doppelgänger- a twin brother! What entails in this serviceable mystery is quite fun, especially the humorous aspect of the ones close to Father puzzled by his behaviour. By the way, I love Tracy Nelson's accent; it's unique and cute. Plus her character is great.
