Bachelor Father (1957)

Never-married attorney Bentley Gregg took on the task (with help from his "houseboy", Peter) of raising his young niece Kelly, after her parents died in an accident. The job was easier when Kelly was a little girl, but now she's in her teens, and beginning to date and venture into the adult world, while Bentley continues to juggle his career, looking after Kelly, and his own romantic life.
