All of the o2l boys are thrilled to go on their second tour, this time on a cruise ship. It will be the first tour without Connor, so the boys aren't feeling as excited as they were during the first tour. Sam and Kian have resumed their crowd pleasing friendship after Kiandrea broke up, but Sam is hiding something big from Kian. Jc and Lia are celebrating their one year anniversary on the tour, but it might be the last year they're together. Ricky is being his usual self, but for some reason, the boys think he's changed. Trevor has to leave the tour early so he can go tour with Lady Gaga. The cruise is full of drama when a familiar face steps on. The question is: will this tour make or break their friendships and relationships?
