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.
