Robin was a chef who came from another comedy show Man about the house. Robin marries Vickie whose father doesn't approve of her choice of husband. They set up their own restaurant "Robin's Nest" with Vickie's Dad as the other partner in the business. They hire "Riddle" as their kitchen porter who has only one arm.
Robin and the father-in-law are always arguing which adds to the comedy factor and later on in the series Vickie has twins.
