When a sailor's young son is taken out to sea by ghosts on his father's boat, the father struggles to get his son back after the superstitious townspeople refuse to be involved with a "haunted" boat.

Looks interesting – here is the same idea tweaked a little, in case it helps:

“When ghosts commandeer his boat and take his young son, a sailor has until dawn to overcome superstitious townspeople and assemble a rescue team to save his boy from purgatory.”

Good luck!
