The plot follows the story of two friends, Cata and Alex, who develop escapist plans about fleeing from their homes in an undeterminate location in the outskirts of Madrid, a seemingly idyllic but actually decaying place.

[8] Included in the 'Zonazine' slate of the 25th Málaga Film Festival, Dragonflies was presented at the Albéniz Theatre [es] on 23 March 2022.

[11] Manuel J. Lombardo of Diario de Sevilla rated the film 2 out of 5 stars, assessing that Knowles' debut feature "smells too much like a photocopy of numerous [common] places in American indie cinema", otherwise incorporating themes of lumpen sorority and escapist desires, a forced criminal-police subplot and a flamenco-electro soundtrack that underpin a "new and artificial" product.

[12] Paula Arantzazu Ruiz [es] of Cinemanía rated it 3 out 5 stars observing that "were it not for the interpretative tête-à-tête of its actresses, [Knowles'] proposal would not advance much further than the author's previous musical video for the song 'Wondering'".

[13] Josu Eguren of El Correo rated the film 1 out of 3 stars, considering that below "the laconic and nihilistic surface of the dialogues" held by the protagonists, the film is based on "such a fragile aesthetic pose" that it threatens to fall apart upon Knowles' attempt to introduce some drops of thriller in the mix.
