The episode starts with Madney's live rehearsal for the concert taking place later that day. On live television, Madney loses her voice, but it becomes clear to the Alpha Team that a spell had been cast. After researching the spell and the missing Semchanach from Otherworld, the Team discovers that a mute siren named Aquaphonis stole Madney's voice. Tara is forced to audition for "Big Star" with a spell that made her voice better. To complicate matters further, obsessed wildlife specialist Henry Delachasse is also hot on the pretty mermaid’s tail, determined to make her the latest addition to his collection. Fortunately, Tara, Cal and Sparrow have boundless imagination and more than one trick up their sleeves…

Serena the terrible Vampire has come from OtherWorld and will do whatever it takes to knock Tara off her stride, taking advantage of the young Spellbinder’s naivety in order to take over the Earth… Fortunately, Cal and Sparrow have got her back and Tara herself has not yet had her say although she is quite annoyed with Sandra who is throwing a party and has invited everyone except her!

Tara must battle Nelos the harpy, an old friend of Sparrow’s father, who has come to Earth to steal a golden scepter hidden in the Manor. Master Chem has strictly forbidden them from taking the staff out of the Manor under any circumstances, but Tara, Cal and Sparrow find themselves with no other choice but to disobey—and hand it over to the harpy: Nelos has cast a spell on Sparrow that has locked her in her Beast form the night she has a date with Edward!

Tara, Cal and Sparrow are faced with an evil conspiracy cooked up by harpies who are exploiting Master Chem’s weakness for gold to drive him crazy. The Alpha Team must bring Chem back to his senses but Tara already has her hands full trying to talk Isabella into lending her some money so she can enroll in a dance workshop she would give anything to go to.

Tara, Cal and Sparrow are up against Serena. This time the Vampire has stolen a unicorn's horn with which she intends to absorb the young Spellbinders' powers. But that’s only the half of it! Henry Delachasse manages to steal the unicorn from Serena! Our three young Spellbinders must simultaneously locate the mythical animal and get rid of Serena... who has absorbed Tara’s powers!
