Edmund takes a flashback to the bench where he and his mom talked about his great-grandfather and his adventures out at sea where he got lost. His grandfathers adventures inspired him to explore the sea himself, but his mother has different thoughts.
Edmund decides that he wants to take a fishing trip outside of Florida down to the Bermuda Triangle to find his great-grandfather and his boat. Even though he doesn't have much experience at sea, his family heritage is filled with sea-like experiences.
Edmund begins to enter the Bermuda Triangle and nervously regrets his decision. But without turning back, the whirlpool brought him into the storm, causing him to enter the unknown world where is great grandfathers presence is.
Edmund suddenly encounters the witch in the sanctuary of the hidden world, and finds out all the other pilots and sailors that disappeared years ago are here in this dimension, including his great-grandfather, who doesn't know he's here yet.
The witch interrupts the reuniting of Edmund and his great-grandfather and decides to put the great-grandfather to work. She puts him in one of the stretch chambers, but Edmund decides to enter the chamber too and ends up stealing the wand.
