The Last Ship 2×06 “Long Day’s Journey” – Hell bent on avenging the destruction of the labs, Chandler tracks the immunes to Northern Florida. Meanwhile, Rachel comes across a secret formula that her mentor, Dr. Hunter, had been perfecting before the Immunes murdered him. The formula holds the promise of mass producing and disturbing the cure, but is incomplete. Venturing further inland, Chandler’s team locates an Immune compound under the control of Sean and Ned. The Captain quickly realizes the Ramseys are not just leading the sub – they’re controlling Immune populations on land, making them a more terrifying foe than initially thought.
