This is a very interesting movie premise that I'm not sure you would have seen before now. It is a very sensitive topic because it demonstrates just how alike all people are of every race and sex. So, people who have religious or racial biases would have been too upset with this movie to have it be made in the past.
So, in this sense it is breaking new ground. Imagine a being a soul who no longer has it's own body. In New Age circles this would be called a "Walk-in". A "Walk-in" can stay permanently in a body (theoretically) but the one in this movie can only stay one day. While (he? She?) is present the Walk-in has most control of the body that day, but by midnight the "Walk-in" is put into another new body every 24 hours. To make this even more interesting, as the "Walk-in" ages through life(it is now approximately 16 to 17 years of age, it ONLY resides for a day each in a 16 to 17 year old body (male or female). And of course a beautiful nubile young white girl falls in love with the Soul the day it controls her boyfriend which is the most wonderful day of both the (Walk-in's and the girls life). And from there it gets more interesting.
