Bon Voyage! Girls Generation, are off on a cruise to Hawaii. Volcanoes, snorkeling and surfing add up to a fantastic vacation away from the glitz and glamour, and all that spy business, but it's not all smooth sailing.

Jessica is blown out of the water by a HUGE family surprise, Passenger's are dieing from sickness, Taeyeon gets sick, and Tiffany spending all of her time with a group of Mean girls. Plus, Sooyoung and Yuri discover a secret stowaway on board.

Here's a hint: He's not the enemy!

Girls Generation have always been a great team, and they need to stick together now more than ever to navigate all the waves in this high-seas drama.
