Sam is mourning the perceived loss of his wife, Christine. He takes out his anger on Sophie. Much of his venom stems from the fact that he has feelings for her.

Sam stumbles into a meeting where a number of Colorado crew members are plotting a mutiny. He takes off running once he realizes what's going down. The men chase after Sam, but only one finds him. It's Prosser. The two of them engage in a brutal fistfight before finally calling a truce to seek cover. The two men debate on whether or not Marcus is a hero or a traitor. Sam ultimately agrees to join forces with the COB and his mutinous men. His conditions are that Marcus is kept alive and that he needs to know everything.
The U.S. government has sent a destroyer to intercept the supply ship China is sending to island. Marcus realizes that the special envoy for the Chinese, Mr. Zheng, has played him very well to make his country look good no matter what happens. The captain of the destroyer, Evan Thorn, is a big fan of the captain of the Colorado. He doesn't believe there's any chance he will ever fire on a U.S. Navy ship. Marcus gives Thorne 20 minutes to turn around before he does, indeed, fire on them.
Grace has an idea to avoid any real damage should they have to fire on the destroyer. James will remove 80 percent of the payload on a torpedo. If they are forced to fire, the destroyer will be sent home in a sling as opposed to a coffin. They have six minutes to get the job done. That time comes and goes. The destroyer fires warning shots at the supply ship. Marcus gives the order to fire on Thorn's ship.
A panicked Grace belays the order until James finishes his work. Marcus is furious. Grace lets him know that the safe torpedo is now ready. Marcus orders it to be fired. It hits the destroyer, but the hull holds together. Marcus promises that the next shot will be a deadly one. The destroyer gets the message. It redirects its course away from the supply ship. Marcus is incensed with Grace, who assures her captain that what she did was done for him.
