The Sixth Secret, mixing mystery, horror and very dark comedy, is a straight-up genre piece, a spooky-séance story involving a group of strangers who are summoned one fateful night, by a mysterious woman, for an experience that might in fact turn out to be otherworldly. The various strangers who are attending the séance couldn't be any more different from one another, and yet, their linkage will soon be understood. And when the bodies start to hit the floor, suspicions run amok, with everyone having a hard time of figuring out who they can, or should, trust.
