Shotgun Wedding

Carlee made up her mind to have her late husband's baby through artificial insemination. But then the sperm bank tells her there has been a mix-up-the sperm used to impregnate her actually belongs to Hal Ward, a world-famous race-car driver who is also an heir to a prominent family. So now Carlee is pregnant with the baby of a man she's never met! She's further tested when a representative of the Ward family comes to say that, as the child will be a successor to the estate, she is advised to marry Hal. Even though the proposal is outrageous, she agrees to visit the manor. There she meets Hal, a very attractive man, except he doesn't seem to be interested in the marriage they're proposing at all!
