Under a scorching sun, Purdey, seventeen, and her brother Makenzy, fifteen, portrayed beautifully by real-life siblings, are left to their own devices. Caught between the carefree spirit of adolescence and the harsh realities of adulthood, they must support each other in this journey of heartrending tenderness, which seems to be the last summer of their youth. Selected in competition at the Cannes Critics' Week, It's raining in the house authentically captures the portrait of a sibling bond facing abandonment and precarity.
