Elisabeth Sparkle is a fading celebrity, a TV fitness instructor who is fired the day she turns 50. Empty of purpose and desperate to try anything, Elisabeth decides to use a black market drug, a cell-replicating substance that temporarily creates a younger, better version of herself.

Easy. Right? If you respect the balance… what could possibly go wrong?
