David takes his two children on holiday to the Adriatic Sea, hoping to hold their fractured bilingual family together. His 17-year-old daughter, Klára, struggling with an eating disorder, falls in love with a local boy, Denis. When he is accused of murder, David rushes the children back home. Klára’s condition spirals, landing her in hospital. The only thing uniting her parents is their need to save her. And desperate times call for desperate measures.

Olmo Omerzu studied at the FAMU film school in Prague, where he developed a passion for making films that explore human nature, family relationships, and people’s expectations of themselves. His first two films premiered at the Berlin IFF and San Sebastian IFF, while his third feature, Winter Flies, earned him the Best Director award at the Karlovy Vary IFF in 2018, along with six wins at the Czech Lion Awards and a selection at the Toronto IFF 2018.
His next film, Bird Atlas, premiered at the Karlovy Vary IFF in 2021.
His English-language debut, titled Ungrateful Beings, had its premiere in the Main Competition of the 2025 San Sebastian IFF.

Ungrateful Beings is a story of a family in crisis, torn apart by guilt and self-denial. At its core, the film asks: how far are parents willing to go to save their daughter from an eating disorder, even if it means crossing the boundaries between truth and lies, care and manipulation? Through this intimate drama, the film explores how adults unconsciously project their own dysfunctions and unresolved wounds onto their children, unable to face their own failures.

“A sly, skillfully sustained Czech drama about a family fractured by anorexia. What at first appears to be a run-of-the-mill trauma drama about a family dealing with the eldest child’s anorexia nervosa gradually evolves into something odder and more original, even blackly comic.”
