A trapped father. A desperate son. A clock ticking down towards certain death - and a fate even more horrifying still…

In the ultimate rescue, life or death is just the beginning!

For mega-church Pastor Alan Rockaway, his teenaged son Jeff and his bride, Jenny, it's little more than a enjoyable submarine ride through Carribean waters. A leisurely end to a week-long Couple's Cruise.

Instead, an accident turns the dive into a terrifying plunge towards the unknown.

Surrounded by horror, with minutes to live and Jeff on the surface frantically planning a daring rescue, Alan battles to fill each tick of the clock with meaning and redemption.

But even the spiritual shepherd of thousands has no clue what awaits.

Everything Alan has always assumed about what lies ahead, along with everything you've always expected in a thriller… will soon be flipped upside down.

A thriller that leaves every danger, every risk and every rescue you've ever imagined-- in the dust.
