Elaine is in the middle of taking an anger management session at the Mill when the power goes off. It seems most of Letherbridge is affected, though not the Campus surgery, so most patients are sent there. Fortunately Rob manages to fix the backup generator, which is good as they are expecting an audit from the PCT. Jack joins Rob as he tries to find out who caused the blackout. One of Elaine's patients is very angry. He has started throwing things and gets really upset when his partner, children and horrid mother all turn up. Daniel's day starts off badly - he's not getting much sleep, and Zara refuses to have phone sex with him. He gets a visit from a young, sexy patient though, who's afraid of the dark.
