The Tomas Crown Affair

In Madrid, Louisa goads Michael into trying some candy, which breaks his tooth. A crooked dentist gives him a crown, adding a smuggled diamond inside. They fly to San Francisco, where Michael is reluctant to see the dentist recommended to get a permanent crown, setting up a plot whereby Michael is pursued by agents trying to retrieve the diamond which he is unaware he has. Louisa wants her beloved Corvette back, while Michael is keeping an old model A for a friend.
