The USS Kentucky, a Trident ballistic missile submarine carrying 192 nuclear warheads, is on a routine cruise when it receives a launch order. Unbeknownst to the crew, the orders didn’t come from the US government. Rogue elements within the Mossad have learned that Iran has developed a nuclear weapon and will detonate it in ten days—in Israel. The only option is a preemptive nuclear strike, and they’re using the Kentucky to launch the attack. With only eight days before the Kentucky reaches the launch site and no way to communicate with the crew, one senior officer must lead a team to intercept and neutralize the Kentucky before the launch.
