Diff'rent Strokes - Season 1 Episode 1 : Movin' In 1986

Multi-millionaire Phillip Drummond, who has agreed to the death-bed wish of his housekeeper to raise her two small sons as his own, welcomes 8-year-old Arnold and 12-year-old Willis into his lavish penthouse. Anxious to make them feel at home, he showers them with gifts and love -- and is puzzled when he learns that the boys are planning to sneak from the lap of luxury back to Harlem. Aiding Drummond in his effort to make the street-wise, ghetto youngsters feel welcome in the affluent white world are Drummond's new housekeeper Mrs. Garrett and his 13-year-old daughter Kimberly.
