Channel 4 has commissioned a single documentary to detail the story of Nazanin Zaghari-Ratcliffe after she was detained in Iran on spying charges.

It will also look Zaghari-Ratcliffe’s husband Richard and his family as he campaigns to bring her home.

Simply called Nazanin it will be produced by filmmaker and journalist Darius Bazargan, and will feature some material filmed by Zaghari-Ratcliffe herself.

On the Channel 4 website it says: "‘Nazanin’ is an intimate access driven documentary – part love story, part political thriller. It has a human story with a big heart and mixes original, observational filming with never before seen material filmed by Nazanin herself about her ordeal.

"We see her young daughter Gabriella trying to cope with the separation from her mother. We see the stress on Richard as he tries to juggle a media and political campaign to free his wife and raise his daughter. We follow Richard as he realises his wife’s detention is deeply connected to the complicated and toxic diplomatic relationship between Britain and Iran and to an unpaid debt going back half a century.

"We have a privileged view of the family in London during the final tense, dramatic days, as a specialist British Foreign Office negotiating team in Tehran wrangle with the Revolutionary Guards over the price for her freedom, as the journey home unfolds and have exclusive pictures of the reunion at a British military airbase."

The documentary will release later this year on the channel.

It was earlier this week that Zaghari-Ratcliffe finally came home after six years of imprisonment to be greeted by her family.
