A beautiful but ditzy young woman dies in a car accident, but is resurrected after she presses the return key on heaven's computer. Problem is, she's not returned to her own body, but that of another recently deceased young woman. She inherits none of her new body's memories, but all of it's genius intellect and amazing lawyering skills. She's also still in love with her boyfriend, who conveniently works with her, but has no idea who she actually is.
My two (female) flatmates are obsessed with it, so I know far more about it than I'd like.
