A:
As an eight-year-old boy, Allen Bauer (David Kreps) is vacationing with his family near Cape Cod. While taking a sight-seeing tour on a small boat, he gazes into the ocean and sees something below the surface that fascinates him, while his older brother Freddie Bauer is walking around the boat fascinated by the women. Allen jumps into the water, even though he cannot swim. He grasps the hands of a girl who is inexplicably under the water with him and an instant connection forms between the two.

After kissing him, she dives into the sea and leaves Allen to return home.
