As a mysterious club owner seeks Elvis's help, a familiar voice sends a message about a door that can't be closed — and the key to keeping it open.

Elvis, Keta and Nancy cross into the underworld to find Ventura and bring him home. Elsewhere, a much older Mayakén displays disturbing powers.

There's a monster at large — that's certain. But no one is quite sure how to kill it ... or why its victims' bones are as black as night.

The crew sets a trap to catch the monster with Lupe's help — and the last of the LDD. But Death is looking for Elvis while they wait.
