Terry has passed his driving test and is working as a mini-cab driver. It's Christmas and Bob and Thelma are off to a dance and have Terry as their cab driver. However Bob and Thelma row when he meets up with an old girl-friend. She asks Terry to drive her home, unaware that Bob & his ex are hiding in the back. The ex forces Bob to drive her home, leading Terry to believe somebody has stolen his car.
