Born in 1984 in Tunisia, Mehdi Barsaoui was "bottle-fed on cinema" by his family. A director father, a producer father-in-law, a video maker cousin: as a matter of course, Mehdi Barsaoui enrolled in film school in Tunis after passing his high school diploma. When he finished his studies, he flew to Italy to complete his training at the DAMS in Bologna. Back in Tunisia, he worked as an editor before starting, in the late 2000s, to shoot short films. Over the next decade, he shot three, as well as two documentaries. Mehdi Barsaoui unveils his first feature film in 2019, A Son.
In the summer of 2011, Fares and Meriem go with their ten-year-old son Aziz for a weekend in Tataouine, in southern Tunisia. On their way back, they are caught in a terrorist ambush, and a stray bullet seriously injures the boy. Hit in the abdomen, Aziz arrives at the hospital in critical condition, and only a liver transplant could save him. Fares and Meriem find themselves embroiled in a race against time to preserve their child's life.
