The feature debut by actress/director Svetla Tsotsorkova is set in a poor area of Bulgaria hit by drought in a hot summer. The 'thirst' in the title refers to yearning for water, but also to something else: thirst for love. The film is about a family that lives on a hilltop. The mother does the washing for several hotels and needs water for that - more than she gets via the local water supply. She calls in the help of a man who, together with his young daughter, goes drilling for a source of water in the hill. The arrival of the two, who set up their tent in the yard, creates quite a stir in the family. The quiet, rather naive son is fascinated by the seductive girl, who also appeals to his father. The girl’s dad - none of the characters gets a name in the film - starts to play a role in the mother's desire for a different and more exciting life. This subtle and subdued film evokes a sultry mood that leads to a dramatic end.
