"In a magical underwater kingdom, the beautiful young mermaid, Ariel, longs to leave her ocean home - and her fins - behind and live in the world above. But first, she'll have to defy her father, King Triton, make a deal with the evil sea witch, Ursula, and convince the handsome Prince Eric that she's the girl whose enchanting voice he's been seeking.

Join Extent Stage Productions with their fifth show. Known for producing high-quality, dynamic performances with young performers, Extent creates unforgettable theatrical experiences for audiences and casts. From musicals to creative workshops, every production is crafted with passion, professionalism and a commitment to excellence.
