They are two different movies, with different scenes. As for the plot, well who really cares; it's Lexus and Stephanie Swift.
Don't know if that helps. If not, re-define your question and I'll try and help you out.
One thing though that I got a laugh out of was, in TNG, Tony Tedeschi plays Debbie's father (and thumps Miss Sharon Mitchell), but in '99, he is the school bus driver who takes a round out of Debbie (Lexus).
