Styx Feet Under

When a demon, Sirk, tries to destroy his human half by killing off his remaining blood relatives, Paige casts a spell that inadvertently blocks all death from occurring. Annoyed that he now has a backlog of work, the Angel of Death insists that the Charmed Ones help him clean up the mess and "kills" Piper so she can help him restore the Grand Design. Meanwhile, Phoebe earns back her power of premonition.
