Capernaum (2018) ✰✰✰✰ (Film4, 11.40pm) Premiere

A 12-year-old boy survives by his wits in present-day Lebanon in director Nadine Labaki’s emotionally wrought drama, which was deservedly nominated for a Best Foreign Language Oscar. Zain (Zain Al Rafeea) lives in cramped conditions with his parents and siblings in Beirut. The family survives by smuggling drugs into prison. It’s an ingenious scheme: the children soak clothes in Tramadol-saturated water, which are dried and taken into prison as gifts for inmates. The illegal operation hits a snag and Zain’s parents decide to raise funds by selling his younger sister Samar (Cedra Izam) as a child bride. The boy vows to make his parents pay and heads onto the streets in search of Samar.
