When Callaghan regains consciousness and discovers that he has been abandoned in the Sahara next to two corpses, he despairs about how to make it back to London without money or a phone. His greatest worry, though, is the loss of the ciclosporin pills that he must take regularly to prevent rejection of the transplants he has been subject to. He eventually makes it to the Mediterranean Sea, where his only alternative to return to Europe is to risk a precarious journey that will take him and several hundreds of hopeful, illegal African emigrants to Italy. After barely surviving the disastrous sea voyage, he continues his eventful journey through Italy to finally reach St Puys - the Swiss clinic where his two face transplants were performed.Knowing that he's wanted by Interpol, at St Puys Callaghan manages to convince Dr Sternmacher to transfer him clandestinely to London in the hope of being reunited with Samantha. When he's unable to find her, the penniless Callaghan pays a visit to the flat he was once the owner of. There, a great surprise awaits him.
