Story without spoilers

Sixteen-year-old Maks and his older sister Emma spend their summer holidays in the Polish countryside, where they have been sent to care for their sick grandmother. What initially appears to be a quiet break from ordinary life becomes increasingly uncomfortable as the siblings find themselves trapped together in the oppressive summer heat.

Their bond begins to shift in ways that are difficult to define, while the boundaries within the family grow less clear. As the tension builds, their grandmother’s frailty takes on a troubling quality, transforming the rural setting into the backdrop for an unsettling transition toward adulthood.

Sick combines family drama with horror, using an isolated countryside setting and a tightly focused family situation as the basis for its unease. The supplied premise points to a story driven by psychological tension, strained sibling dynamics and a gradual blurring of personal boundaries rather than broad action or spectacle.
