In the summer of 1914, the transatlantic ocean liner carrying Grace Winter, 22 and her new husband Henry suffers a mysterious explosion. Forced into an overcrowded lifeboat, newly widowed Grace Winter battles the elements and her fellow survivors and remembers her husband, Henry, who set his own safety aside to ensure Grace's. The survivors quickly realize the boat is over capacity. For any to live, some must die.

In 1912, thirteen-year-old Albert considers his younger sister a pest, but things change when they travel with their mother and uncle aboard the Titanic and are caught up in its tragic sinking.

While unpacking a special collection of Titanic artifacts at the local museum, best friends Tucker and Maya touch a canceled ticket and find themselves transported back to Queenstown, Ireland, where the Titanic is boarding--can they figure out how to save a new friend, and still get back to their own time?

Tucker and Maya use the final Titanic artifact to return to 1912 one last time to rescue Liam and join the survivors in the lifeboats as they wait for rescue.
