Company PA Dani Foster is left in fear of her life when a suspect package delivered to her office explodes, covering her in a white powder.
The package, addressed to Dani’s high-flying boss, Alan Cooper, arouses Dani’s suspicions when she opens it and spots some protruding wires.
Dani immediately alerts Cooper who gets straight on to the Sun Hill cops.
As she waits for the police to arrive, terrified Dani daren’t let go of the package in case it triggers an explosion.
When Sgt Callum Stone and Pc Ben Gayle arrive at the company’s offices, they find Dani in a distressed state still clutching the package. Cooper, meanwhile, explains to Ben exactly what has happened.
Callum ushers everyone else out of the offices and tries to calm down Dani. But she panics and throws the package to the floor where it explodes, covering her in a white powder.
Callum instantly moves to seal the office – with Dani inside – to prevent the possibly poisonous powder infecting anyone else. Cooper tries to rush to his PA’s aid, but is restrained by Ben.
As Dani screams to be let out, Callum begins sealing the door…
As he works, he tries to reassure Dani, but she’s inconsolable.
Tests prove that the powder is harmless and Dani is finally released from the office. The Sun Hill cops then quiz Cooper in front of his pregnant wife and his brother, David.
As the investigation gets underway, it emerges that the package was delivered by a courier who had recently harassed Dani and clashed with Cooper. Callum goes to arrest him.
But the courier, Andrew Stevens, puts up a struggle, and Ben has to help subdue him.
Finally, the pair get him in the car and take him in for questioning.
The case then takes a sinister turn when Callum finds bomb-making equipment in the home of Cooper’s brother David, who bears a grudge against his sibling. Callum and DC Grace Dasari trace David to a local park.
Ignoring commands from DI Neil Manson, Grace decides to approach David, who is clearly disturbed and carrying a rucksack. What does it contain?
David, who had been sacked by his brother not long ago, opens up to Grace about their troubled relationship.
Having explained that his brother has everything he could possibly want in life – a high-flying job, a beautiful wife and children – but is jeopardising it all by having an affair with Dani!
Sensing that David is near to breaking point, Grace checks his bag, and is relieved to find it is empty.
But then David bursts into tears and explains that he’s sent another package – this time to his brother’s home…
