A half-mortal, half-witch teenager named Sabrina Spellman discovers on her sixteenth birthday that she has magical powers, and must learn to navigate both the demands of ordinary high school life and the unpredictable consequences of her spellcasting. She lives with her two eccentric aunts, Hilda and Zelda, who guide her through her witchy education, alongside Salem, a wisecracking cat who is actually a witch serving a punishment. The series balances comedy and coming-of-age drama as Sabrina tries to keep her supernatural identity secret from her friends and boyfriend.
