When a young woman is dressed like a bride and drowned in a bath, it triggers a spate of ghoulish wedding-themed murders in Great Worthy. The case takes Barnaby and Jones to a donkey sanctuary, a heritage steam railway and a pub run by an ex-copper and former brothel madam. With the serial killer still at large, could history be repeating itself? Guest stars include Pam Ferris (Call The Midwife).
