A tall, slender Betty Boop is in charge of an automobile hospital, where cars are treated like human beings. After singing the title song, Betty tends to such patients as an ice wagon suffering from a terrible cold, a wobbly car with a bad case of "auto intoxication", and a race car that has been "living too fast." There's also the nervous "jittery buggy", an Irish-accented police car with flat "feat", and an insane "cracked cylinder case." But Betty and her highly efficient staff ministers to all the patients, not only curing them but giving them a complete overhaul. The best is saved for last when Betty tackles a most unsual emergency case involving an "expectant" auto.
