Snow drifts over East High as the Wildcats reunite for a holiday benefit that could save the drama program. Troy trades the court for the piano, Gabriella maps a future that might be miles away, and Sharpay arrives with a sparkle‑bomb plan only she could stage.

Rehearsals burst into candy‑cane choreography, locker‑hall harmonies, and a snow‑globe duet that melts the gym. Old rivalries thaw, new crushes spark, and a last‑minute blizzard threatens opening night. When the power cuts, the crew turns flashlights into spotlights and the audience into a choir. Once a Wildcat, always a Wildcat—especially at Christmas.
