Bernardo is an undertaker. He runs his mortuary business in the same house where he resides. In the front, he has his clients.

But when a malevolent entity enters the scene, it wreaks havoc on the already fractured household.

From Harlan's dysfunctional family to his devoted staff, Blanc sifts through a web of red herrings and self-serving lies to uncover the truth behind Harlan's untimely death.
