Things change with the arrival of family friend Isabelle (Erja Malatier) however, whose constant presence convinces Nicolas that their parents have set up a plan for them to get married in the future. Deciding to try and solve the problem himself, Nicolas recruits his new companions to help him come up with a number of ingenious schemes to try and make Isabelle's parents leave the resort and take her home.
