It's October 1945 in the SF Bay Area. World War 2 is over. The American service men who fought in the Pacific theater are coming home. Doctor James T. Walker, an esteemed physicist who worked on the Manhattan Project, the government project that developed the atomic bomb that was dropped on Hiroshima Japan two months earlier, mysteriously disappears.

It's up to his son, JT and one very smart black Labrador retriever named Mickey, to uncover what happened. JT has issues of his own, having just returned stateside. During the war he served as a military policeman aboard the ill-fated USS Indianapolis, which was sunk by a Japanese submarine near the end of the war. Stranded in the Pacific Ocean for five days the survivors of the Indianapolis suffered through the worst shark attacks in recorded history. Recovered from a life-threatening shark attack, but still suffering from the trauma of his ordeal, JT, with Mickey's help, struggles to uncover the truth about his father's disappearance.
