After the Home Office suspend Section D to investigate Ros’ betrayal, Connie is approached by former IRA member Davie King, who still bears a grudge against Harry. King orders that all of Section D must assemble at the location of a bomb he plans to detonate in London. If they refuse, hundreds of civilians will die.
Harry realises that King must have been ordered to target Section D by someone else – someone who needs Section D out of the picture. As the team congregate at King’s designated spot, Jo and Ben try to work out where King is situated to try and elude his surveillance.
With just minutes to spare, Ben and Jo must take down King, while Adam and Harry try to defuse the bomb. Can they avoid a disaster – and find out who commissioned their murder?
