A pair of aging starlets fall from grace after they both succumb to their own vain tendencies. They both find solace in a youth potion that will allow them to live forever, with one catch: They aren't actually alive, and though they can still think and speak and give an outward appearance of being alive, they have no heart beat - making them walking corpses. Quite literally, nothing can kill them, not even dismemberment - something the both of them learn as they take out their frustrations on one another.
Realizing that it would be pointless if they destroyed their eternally youthful bodies over petty arguing, they hatch a plan to make a mutual friend also drink the eternal life potion, so he can help them maintain their beautiful appearances until the end of time. Unfortunately for the two women, he's not so keen on living forever.
