1. Startled Deer
Aboard the HMS Goliath, a British stealth nuclear submarine the team are participating in a training exercise with the Americans. However, the mission goes wrong when live missiles are fired at a U.S. boat. Lieutenant Jack Trainor and Commander Alison Fairbanks bicker over who has responsibility for the mistake, and Jack believes that Captain Paul Wade is not actually a real captain, having known a Captain Peter Wade while in training. With a press pack onboard, the crew decide to stealthly slip away before releasing the press pack into a lifeboat. The crew resubmerge before later surfacing and coming under fire from Chinese pirates.
2. Special Relationship
The submarine finds itself off the coast of South Africa and has fourty-eight hours of downtime, which allows some of the crew to enjoy the surface while other are stuck doing exercises. However, they receive orders to welcome aboard a team of U.S. Navy Seals who are to spend some time with them. Alison intends on enjoying the company of one of the men, while Jack wonders whether their visit will be a ticket for him to get away. Captain Wade arranges for the visit by having fish and a beachball delivered to the boat in anticipation of their guests.
