Charmed - S01E22 - Déjà Vu All Over Again

A warlock repeatedly attempts to kill the Charmed Ones, with a help from demon Tempus turning back time after each failure so that he can try again. However, because of the endless time loop and her power of premonition, Phoebe experiences a number of strong cases of déjà vu and is able to figure out that there are evil forces after them.
