22-year-old Agnes Akom has been reported missing, but what begins as a search for a missing person develops into something potentially far more serious. Agnes has not been seen for eight days and her usually extensive use of social media has stopped completely. As fears for her safety increase, her case is passed from local police to the Specialist Crime Unit who handle the Met's most complex crimes.Agnes' last known sighting is on Cricklewood High Street in north west London. CCTV from the area shows her getting into a silver car registered to a 66-year-old man, Neculai Paizan.Investigations into Paizan reveal he owns a storage container on an industrial estate, it is immediately searched, but Agnes is not there. However, detectives discover a CCTV camera pointing at the entrance to the container. As they begin watching footage from the day she disappeared, they make a worrying discovery, Agnes can be seen walking into the container with Paizan, but three hours later Paizan walks out alone.When Paizan is brought in for questioning, he admits going into the container with Agnes but claims they came out together 20 minutes later, directly contradicting the evidence from the CCTV. As forensic examination of the container reveals traces of blood, detectives must now try to discover where Agnes' body is.
