Tom is appalled by the informal way Arthur runs his practice but both men combine to try and talk sense into their cleaner Edie McClure, sister of pub landlady Phyllis, whom Edie disdains for giving up on her marriage. Edie has a weak heart but is determined,against doctors' advice, to see through her seventh pregnancy as she has six daughters and is desperate for a son. Matters are taken out of her hands when she miscarries but reconciliation with Phyllis follows. Eddie,the hunky garage mechanic ,asks for advice from scrap-dealer Jean about dating Tom's teenaged daughter Helen but Jean misunderstands and assumes he wants to date her whilst Tom's son Michael gets revenge on a bullying schoolmaster.
