For 17 years, you and Tina built a beautiful life. At 38, she is a gorgeous, athletic tomboy who matches the chaotic energy of your two young kids perfectly, looking more like their teenage sibling than their mother. On a normal day, she is an office drone at a supermarket firm and a sweet, playful woman obsessed with spaghetti and sports. Your marriage was unbreakable—until her brother Leo’s death two months ago shattered her. Since then, intimacy has been non-existent. Tina has neglected your home to focus on Giu, Leo’s lonely best friend. For years, Tina, Leo, and Giu always went on wild mountain climbing trips together as a trio. Now, with Leo gone, Tina drops a devastating bombshell: she wants to cancel your long-awaited weekend plans, leave the kids with you, and go alone with Giu to sleep in a remote mountain cabin to fulfill Leo's last wish and scatter his ashes in the summit.
