Charlie owns Speedy Taxis - a man devoted to his work, much to the distaste of wife Peggy. Fed up with coming second to a fare, Peggy hatches a plan to set up her own rival firm, Glamcabs. To her surprise and Charlies dismay, Glamcabs is a raging success and threatens to put Charlie out of business. There's only one way to save Speedy Taxis...

One of the better films, the relationship between Sid and Hattie sets the scene for the domestic situation in many of its successors. Hawtrey fills in admirably for the absent Kenneth Williams with his wide-eyed portrayal of the delightfully inept Pint Pot. The script is one of the better ones of the early Carry Ons and is played to perfection by all involved; the only let down is the slightly twee chase sequence at the end of the film, but this is more than compensated for by the earlier scenes where a despairing Sid is trying to show his incompetent drivers the ropes. Jim Dale makes his first Carry On appearance in a cameo as the expectant father.
