Sister

Simon, a twelve-year-old, funds their life by stealing ski equipment from resort guests. He refurbishes the gear and sells it to buy food and pay for Louise's lifestyle. This illicit routine places him in a caretaker role for his older sister.

Louise is selfish and unreliable, frequently leaving Simon alone while she pursues relationships or freeloads off men. She struggles to hold down a job and seems indifferent to Simon's hard work. Their dynamic is strained as she uses him to prop up her lifestyle.

Simon helps Kristin with her son's equipment and introduces himself as Julien. They have lunch together and Kristin pays the bill, which surprises him since he normally has to contribute. He learns that kindness from strangers can be rare.

Mike, a resort employee, catches Simon hoarding skis. They strike a bargain: Mike provides a storage space in exchange for some of the equipment. The deal gives Simon a way to store his stolen goods while continuing the theft to make money.

Louise returns from her trip with Bruno and settles in for the night. In the car, Simon lies about where he lives, claiming to be from a 'fucked-up' family as Bruno chats them up. The moment hints at a deeper tension between them.

During the ride, Simon reveals to Bruno that Louise is his mother, not his sister. Bruno forces them out of the car and they walk home, the truth kept temporarily hidden but threatening to explode.

That night, Simon pays Louise to sleep in her bed. Louise admits she kept him to avoid loneliness and to defy those who said she should not keep him. After Simon falls asleep, she sneaks out to drink and is found unconscious the next morning.

Simon carries Louise home with help from other children and realizes they have spent all their money. The betrayal of their finances becomes a painful wake‑up call for their fragile arrangement.

With no income, Simon tries to recoup funds by returning to the resort with a younger child. Mike rebukes him and ends their partnership. Simon hides the skis anyway and raids the changing room, but finds only small change; the hidden equipment is found, and he is thrown out.

Without money, Simon asks an old customer for food and Louise cooks for him. She then takes him to her new chalet cleaning job and hands him some money, saying she does not want to be in his debt. It marks a fragile alliance still tethered to survival.

They end up at Kristin's cabin, where Kristin is disappointed to learn that Simon lied about who he is. He apologizes, but she rebuffs him and remains distant.

Kristin later confronts Louise and Simon about a missing watch. Simon's pockets are turned out and the watch is found in his pants; Louise and Kristin clash, and Kristin dismisses them without offering help.

Louise grows furious that Simon cost her a job, and the two argue harshly. The conflict underscores their volatile dependence and dwindling options as season's end approaches.

As the season ends, Simon goes to the resort to seek work but is refused due to his age. He takes a cable car down while Louise goes up, and in a final separation the two cars part with Louise shouting to him from the glass.
