An Iranian soldier sits in an MI6 safe house. He may only be a corporal, but as chauffeur to a top general he knows many secrets, such as the location of nuclear sites. But the Corporal won't talk unless they bring his wife out of Iran, too. So the SAS are asked to do the job - but they say it's impossible. Which is how Zach Bennett, a university drop-out recruited for his language skills, and a rag-tag team of three ex-soldiers find themselves on a mission to Tehran.
If they are caught, it will mean certain death. And the Corporal's wife - fiery, independent and beautiful - is not the kind of person Zach was expecting.
In fact, she's not like anyone he's ever met in his life.
