Police officers from the UK and Uganda trace a woman who fled the UK after killing her own daughter. Police in Yorkshire pursue a man who used a light aircraft to smuggle cocaine, and a team of officers in London are on the hunt for a man who should be in prison in Italy for committing rape and serious assault. And for criminals, Spain is a lot more than a holiday destination. It’s also a gateway into Europe for those who control the smuggling routes, and a bolt hole for those wanting to lie low. Hunting them down is an elite part of Spain’s Guardia Civil known as the 'Fugitives Unit’.
