The Little Mermaid

The mermaid Ariel, daughter of King Triton, is fascinated with humans. She falls in love with the human prince Eric after she rescues him from a shipwreck. Condemned by her father for engaging in illicit contact with the surface world, Ariel then receives an offer from the scheming sea witch Ursula - Ursula will turn her into a human for three days, but during this time she must win the kiss of true love from Eric otherwise Ursula will own her forever. Ariel agrees but to add to the difficulty Ursula also takes Ariel's voice as price of the deal and then schemes to ensure that Ariel fails.
