On top of a stunning mountain in Israel, award-winning inventor Chase Johnson proposes to his girlfriend, Abby. She cries, "Yes," and they celebrate as their mutual friend, Tiffany, takes photos.

Chase runs to get his buddy Billy, so the four of them can celebrate together. When the men return, all they find are shattered cell phones and a broken camera. The girls have vanished.

Chase reports the disappearance to the local police, embassy, and social media, but they offer little help. Desperate to find her, the men use their own innovative technology to follow leads from one end of Israel to the other.

When all hope seems lost, Chase discovers Abby and Tiffany's abductors, an ancient pagan cult still alive and well. And unless Chase can win a race against time, the cult is ready to make Abby a human sacrifice at their temple called The Gates of Hell.

Get ready for a thriller that will set your heart pounding and your mind racing long into the night.
