Strange Days at Blake Holsey High (2002)

S2E10 Hemispheres

Corrine is ready to audition for Magnet 360°, but Marshall's blunt reminder that she's a math genius, not a singer, shakes her confidence. As she studies her reflection to see if her fear is visible, the mirror suddenly glows with BHH energy and pulls her through. She lands in a strange, reversed world where she meets alternate versions of her friends—each one a mirror-image twist. It's a bizarre new reality for Corrine to explore, and nothing is quite what she expected.
