Arriving into Washington in 2023, Adam plans to officially put his testimony on the US government record – if they will let him – then walk off into the sunset. The past seven years have taken a toll on Adam, progressively broken down by the fight. He is confused as to why his government seems to have turned against him. In his mind, this is his last stand.

But as with everything in the story of Havana Syndrome, nothing is straightforward – with the US government and the intelligence community keen to shut the door on the saga.

In this final episode of Havana Helmet Club, Jennifer Forde and Sam Bungey try to pull all the pieces of the mystery together.
