Ghost Flight Path

I want to adapt this novel into a short film. (I'm a film and television directing student.)

Inspired by the Cthulhu Mythos. On the vast, boundless ocean sails a luxury cruise ship called the Skull. Renowned for its lavish amenities and attentive service, the ship nevertheless conceals a horrifying secret. Every seven years, the Skull embarks on a special round-the-world voyage, and each time, a string of bizarre events unfolds. Passengers and crew vanish one after another, as if swallowed by the sea.
