Casualty (1986)

Season 17: Episode 14

A Christmas-tree thief chops off his own thumb and a farmer injures his leg while trying to catch him. Things don't look good for the thief's thumb and there's a valuable lesson to be learned about the care of severed digits. The plastic surgeon suggests replacing the thumb with a big toe. It's then revealed the bloke who nicked the tree is the brother-in-law of the farmer who has been brought in with the injured leg, and therein lies a 15-year family feud. Jack is forced to silence a victim of his father's empire when Eddie's gang confronts him. Lara spends an evening with Harry's kids, unaware of Beth's true feelings.
