A runaway electric saw is brought to life by a naughty youth, who breaks into a shed. When it's blown up, the youth is not looking too good. Laura casts doubt on a young mother and Duffy sees a nursing colleague doing possibly the worst thing a person in nursing, could do. Also, Jack's dad gets what has been coming to him and there's a Mr Lambert who is still fighting the Korean War. Simon's flirtation with a new arrival infuriates Colette, and Josh seems blissfully unaware of his marital problems.

Harry is determined to rid the department of time-wasters. But when a private patient is brought in suffering from post-operative complications, he wonders if he has been too quick to judge.

Josh and Comfort stumble across a badly-injured Jack, while Dillon's Good Samaritan skills are put to use on a neglected teenager with learning difficulties. Meanwhile, Simon's new girlfriend, Jane, visits the department with a close friend suffering from a mystery illness.

It's trying times for everyone in this episode. While Josh can't accept that he and Colette are history, receptionist Jack is having to do some dirty work for his gangster dad. Meanwhile, paramedic Fin's daughter Emma, is brought in to casualty with what looks like a nasty tummy bug. Fin is busy tending a young footballer with a broken leg and can't attend to her and she gets worse. Not the best time for Charlie to return and there's a further blow for him when Duffy announces she's leaving to get married and set up a business.

Duffy's intended, Ryan, is obviously a wrong ‘un and yet everybody is wishing her well as she leaves Holby to set up home and a business with him. Receptionist Jack's foray into his gangster dad's twilight world forces him to make a big decision. Elsewhere, Harry and Beth's relaxing sailing trip becomes a rescue mission when he spots another vessel in distress, which turns out to be packed with illegal immigrants from Kosovo. But not all of them are as helpless as they appear… The police close in on Jack.

It looks as if long-suffering Duffy's beautiful dream may turn into a nightmare, as security guard Ryan proves to be nothing like the perfect man she'd hoped for. Dillon and Colette take it upon themselves to fight it out for her old job, and clash over the treatment of a malnourished toddler. Meanwhile, things seem to be running rather more smoothly for Tony and Ben, who decide their evening together was perhaps more than just a non-night stand.

Ryan is still AWOL with Duffy's money, and this week Duffy puts her house up for sale in order to get the moeny back. Fin and Comfort are called to a suspected break-in and attack, and at the hospital Lara is treating her. Lara is concerned about her and offers her the chance to talk, she doesn't take it up. Harry treats Anna's mum, who wants to meet boyfriend Merlin. Tony asks Ben to move in with him. Comfort tries to talk to the attackee(referred to as battered wife from now on) and tells her that she is always in the eyes of God. Colette maenwhile is doing a pregnancy test in the toilets, which comes out positive. It is Simon's baby.

Events take a tragic turn when Jeff tactlessly threatens a highly-strung man while on a call-out with Nikki, and the arrival of an attractive neurologist causes problems between Harry and Charlie.

Josh, in his new job as duty officer, clashes with Finlay over the treatment of a heart attack patient, while a face from the past ruins Ben's plans for a romantic evening with Tony.
