A freak chemical spill endows teenager Alex Mack with special powers, including the ability to "zap" electric shocks, liquefy into a puddle, and move objects with her mind. Fearing discovery, Alex only shares her secret with her whiz-kid sister, Anne, and her trusty best friend, Raymond. But will any of Alex's marvellous new abilities help her face the awkwardness of junior high? A replacement for the popular CLARISSA EXPLAINS IT ALL, this hit Nickelodeon series mines similar territory with its savvy young heroine dealing humorously with the complications of adolescent life. Included here is the show's complete first season, which features appearances by a young Jessica Alba.
