The hospital is hosting a charity Grand Slave Auction with Statham, Caroline, Guy and Lyndon all up for bid and while there is high competition for some, others aren't so lucky. Meanwhile Caroline falls on Sue's bad (and murderous) side when she admits to having feelings for Mac, but Mac surprises them all by revealing his new girlfriend Lady Emily and by the announcement that he his leaving the hospital after being offered a consultancy position in Sheffield. Martin decides that the way to win Caroline's heart is by being a bastard, Joanna finally finds out where she stands with Lyndon and Harriet is called into the school to talk about her troublesome son.
