Father Brown and a guest undertaker -widow mother Ruth having an old feud with the local Peter Blackstone- see to the funeral of baker-son Alexander Moore, who got decapitated in an accident. the next night, the corpse is stolen from the freshly buried coffin, and his simpleton kid brother Ian swears to have seen him wander around, resurrected for his secret girlfriend, Blackstone's daughter Catherine. Peter is arrested after reporting he found the non-decapitated corpse in a coffin in his parlor, but Brown's team patrols the church graveyard and tracks down what actually happened after preventing another grave robbery.
