Sunday's Illness (Spanish: La enfermedad del domingo) is a 2018 Spanish drama film directed by Ramón Salazar which stars Bárbara Lennie and Susi Sánchez alongside Greta Fernández, Richard Bohringer and Miguel Ángel Solá.

[1] Anabel is hosting a large dinner party and recognises one of the catering staff as Chiara, the daughter she has not seen since she abandoned her at the age of eight over thirty years ago.

Chiara drives Anabel into the countryside to a remote community where she lives in her childhood home.

During the following days the tensions build between the two women, and Chiara refuses to reveal what she wants to achieve, saying that she doesn't need or want to forgive Anabel.

[6] Wendy Ide of ScreenDaily wrote that "both [Sánchez and Lennie's] performances are phenomenally good; the two women who at first seem like opposites are gradually drawn together by something primal and unbreakable".

[4] Jonathan Holland of The Hollywood Reporter described the film as "beautifully crafted, spectral and emotionally punchy", also considering that it is "marvelously played by Spanish actors Susi Sanchez and Barbara Lennie".
