Lisa, a physiotherapist, starts her new job in an institution for people with learning disabilities. She meets Mark, who is actually just being kept there temporarily and who initially reacts to her in a dismissive, almost aggressive way.

Lisa is reprimanded by her superior because of the promise she made to Mark.

Martin's boys get into a fight, which threatens to derail the whole expedition to climb Gran Paradiso. Will Lisa manage to calm everyone down?

Martin, Lisa and the boys are now on the bus headed for the mountains. Mark makes himself unpopular again, and then it turns out that they have a stowaway on board...
