A promise.

A shipboard romance.

One transposed number threatens to sink love before it gets started.

With the age of 28 looming ahead and Tatum Jackson still unmarried, she made a vow to enjoy her birthday on a cruise ship bound for Hawaii. She runs into, literally, a handsome man and enjoys a romance movies were made of.

When the cruise ends, she agrees to continue the relationship with Eric Carlson via letters. Then one simple mistake leads Tatum to think it all a lie.

Will fate intervene once again and save these two hearts?
