The Bluestone 42 team experience a tough roadside operation, but it's the new padre, Mary, who really grabs the attention of bomb disposal expert, Nick.

Nick is desperate to find some decent food to use in an attempt to seduce Mary, whilst Simon gets into trouble on roadside operations.

After Bluestone 42 join a midnight raid on a bomb factory and rescue a kidnapped Danish aid worker, they find more than they bargained for; elsewhere, Simon tries to get a book deal for his memoir.

Mary reveals a secret about her past before she became a padre and Nick tries to take full advantage; Bird is offered a promotion.

Nick tries to prove he is not superstitious to the padre, while Simon tries to earn respect by joining in dangerous homemade games with Mac and Rocket.

Nick and Simon help each other to learn to dance, while the arrival of vet Parikh reveals Bird as a terrible flirt.
