A marine biologist who secretly wants to be a lounge singer, but is tone-deaf, and no one will tell her she sucks at karaoke. She gets brutally attacked by a school of dolphins while half way through the chorus of Barbra Streisand's 'Rain on My Parade' and ends up becoming an inspirational public speaker for the maimed, tone-deaf community.
And she's Canadian... sorry, I left that detail out.
