“Mary.” A Haunted House Story Set On A Sailboat...

[Gimpdiggity]

I’m not going to lie...this trailer gave me the creeps.

Garys there and so will I opening day!

Looks too jump-scare-y for my tastes, but it's written by the writer of "The Shallows", so it's sure to go completely bonkers in the third act.
I'm betting the boat explodes in a giant fireball at the end, after Gary's wife goes all Rambo on the ghosts with a flare gun.
