It’s a week before the presidential elections when a bomb goes off in an LA shopping mall. In London, armed police storm Heathrow Airport and arrest Sajid Khan.

His daughter Aliyah entered the USA with the suicide bomber, and now she’s missing, potentially plotting another attack.

But then a woman called Carrie turns up at Sajid’s door after travelling halfway across the world. She claims Aliyah is with her son Greg, and she knows where they could be.

Back in the US, Agent Shreya Mistry is closing in on the two fugitives.

But the more she investigates, the more she realises there is more to this case than meets the eye and suspects a wider conspiracy.

Hunted by the authorities, the two parents are thrown together in a race against time to find their kids before the FBI does, and stop a catastrophe that will bring the country to its knees.
