Plot Outline: On board a flight over the Pacific Ocean, an assassin, bent on killing a passenger who's a witness in protective custody, let loose a crate full of deadly snakes.
So is Samuel L. Jackson the assassin, or the passenger, or the U.S. Marshall or Secret Service or something who is in charge of the passenger's safety?
Either way, sounds like two thumbs up!
I'll go see it with you Bobby.
