When Claudia decides that she does not want to wait for the disease to ruin her body, her partner, Flavio, who has not separated from her in the last forty years, puts into motion their old plan to end their life together in Switzerland thanks to the help from a voluntary assisted dying association. Meanwhile, her daughter Violeta becomes the involuntary mediator between her parents and everything they leave behind while she tries to find her place in this story of unconditional love.
