Gus (George Winslow) is the young son of divorced industrialist Dave Jennings (Richard Widmark). Unable to cope with Gus' mischievous streak, Jennings places the boy in a day-care center. Gus' teacher Lydia Marble (Joanne Dru) manages to curb the boy's prankishness, and along the way falls in love with Jennings. Enter the villainess of the piece: Jennings' ex-wife Joyce (Audrey Totter), who claims that the divorce is invalid and demands a huge sum from Jennings, lest she claim custody of Gus. In the end, it comes down to priorities: does Jennings value his son over his money, or vice versa? My Pal Gus is no Kramer vs. Kramer, but it does pass the time in an agreeable manner.
