Someone, or something, is haunting the ship. That is the only way to explain the series of misfortunes that have plagued the passengers of the Titanic from the moment they set sail. The Titanic‘s passengers expected to enjoy an experience befitting the much-heralded ship’s maiden voyage, but instead, amid mysterious disappearances and sudden deaths, find themselves in an eerie, unsettling twilight zone. While some of the guests and crew shrug off strange occurrences, several—including maid Annie Hebbley, guest Mark Fletcher, and millionaires Madeleine Astor and Benjamin Guggenheim—are convinced there’s something more sinister going on. And then, disaster strikes.

Years later, Annie, having survived that fateful night, has attempted to put her life back together by going to work as a nurse on the sixth sailing of the Britannic, newly refitted as a hospital ship to support British forces fighting World War I. When she happens across an unconscious Mark, now a soldier, she is at first thrilled and relieved to learn that he too survived the tragic night four years earlier. But soon, his presence awakens deep-buried feelings and secrets, forcing her to reckon with the demons of her past—as they both discover that the terror may not yet be over.

Featuring an ensemble cast of characters and effortlessly combining the supernatural with the height of historical disaster, The Deep is an exploration of love and destiny, desire and innocence, and above all, a quest to understand how our choices can lead us inexorably toward our doom.
