Kim Bassinger plays the hapless Harmony, born during an Elvis concert
and ever after linked in some way to the King. While on the road hawking
lipstick, she accidentally kills a couple of Elvis impersonators and ends up
on the run from the FBI.

So, in an unlikely coincidence, does a depressed advertising executive
whose path intersects romantically with hers as the pair head toward
the film's climax at an Elvis convention in Las Vegas.
