It's 1968, a time when global upheaval seems the norm. The war in Southeast Asia rages along with prolonged civil unrest at home. Amongst this, turncoat Navy Warrant Officer JOHNNIE WALKER begins an extended relationship with the Soviet Union by selling top-secret crypto key lists to them to fulfill a voracious appetite for the good life. This prompts the Soviets to order their friends, the Democratic People's Republic of Korea (DPRK), to seize the USS Pueblo (AGER 2) steaming in international waters off the coast of North Korea. The Pueblo carries the KWR 37 coding machine, allowing the Soviets to read the codified material Walker had sold to them. And then it gets worse as President Lyndon Johnson gives up and refuses to run for a second term. Right after that, Martin Luther King and Bobby Kennedy are assassinated two months apart. With the nation still reeling and grieving, the Democratic National convention is disrupted by riots that August. Caught in the morass is Naval Academy graduate Lieutenant (j.g.) JERRY INGRAM. Just out of flight school, Young Ingram is a is a freshly minted P-3 (4-engined submarine hunting patrol plane) co-pilot assigned to a P-3 squadron in Sigonella, Sicily. En route to his first duty assignment, Jerry falls in love with RITA HERNANDEZ. A Mexican beauty who has made it big in New York's fashion world. They settle in Catania nearby and Jerry, who squeaked by in life, due to the influence of his father, Vice Admiral TODD INGRAM, suddenly realizes he is involved in serious bustiness. He vows to bear down and make a go of it, as a pilot and as a husband. Instead, he comes home one night to find Rita in bed with MICHELANGELO RUGANI, a wealthy and handsome Italian ski-bum and Winter Olympics wanna be who also represents the Rugani family's Enzio line of Fragrances. Jerry beats the daylights out of Michelangelo and is censured by the U.S. State Department and the U.S, Navy for his trouble. Politics are in play as the Navy hangs an article 133 charge, conduct unbecoming an officer, around Jerry's neck but whisks him off to another duty station to get him out of sight. With Jerry's disappearance, a vengeful Rugani family (Poster- boy Michelangelo has lost three front teeth and has two broken ribs) sends Michelangelo's body guard, Giorgio Michelleti, strong man of the Salvati Mafioso family, of Sicily after Rita who has taken refuge in her father's vineyard high in the hills above Vera Cruz, Mexico. Jerry is assigned to squadron VP 72 at Barber's Point, Hawaii. From there and other bases, the U.S. Navy searches for Soviet submarines that seem to be popping up like ten-pins all over the Pacific. And he is uncomfortably close to his father who is commanding officer of the top-secret Fleet SIGINT Operations Control Center in Kunia, Oahu, Hawaii. Todd Ingram's on-again, off-again friend is Soviet Navy Captain First Rank EDUARD DEZHNEV who he first met in 1942 (A Code for Tomorrow). More recently, they re-kindled their friendship when Dezhnev helped save Ingram's life right after Japan's surrender in 1945 (Edge of Valor). Over the years, Dezhnev declines the invitation of CIA agent OLIVER TOLIVER to come over to the other side. Desperately earnest, he wants to somehow help change his beloved Rodina for the better. And Eduard is proud of his son, Starshiyi Leytenant VLADIMIR UTKIN DEZHNEV, also a newly minted naval officer. Young Vladimir is highly regarded for his computer skills and is attached to the K-129. But the soviet boomer sinks in the Central Pacific with all hands. Only Jerry Ingram, while on a special assignment aboard an American submarine, sees through the periscope what really happened to the K-129. And now, the KGB closes in on Dezhnev. With his fiancé, ROXANNA UTKIN, he is barely a half-step ahead of them as they scramble aboard a Black Sea ferry in Sochi, Russia, and make it to Trabzon, Turkey, and ultimately American hands.
