The last time anyone saw Hodei Egiluz, a 23-year-old computer engineer from Spain, was on a night out in the Belgian port of Antwerp in October 2013. Hodei is one of roughly 10,000 people who disappear in Europe every year. But his case has sparked a remarkable response. Practically his entire home town in Spain got behind the Belgian police search in one way or another. The search for Hodei triggered a campaign which eventually drew in figures such as footballer Ronaldo and the prime minister of Spain. But two years on Hodei is still missing. For Crossing Continents, Neal Razzell retraces Hodei's last hours in Antwerp and tries to unravel the mystery surrounding his disappearance. Producer: Charlotte McDonald.
