Westleham Village 1947. It's the Westleham village show and with the war finally over, everyone is looking forward to a pleasant day. But newcomer, Martha Miller doesn't share the excitement. Because since her husband Stan left for work one day and never returned, Martha has been treated as somewhat of an outsider in Westleham. The village gossip is that Martha must be to blame. Martha hopes she can win her fellow villagers over with her delicious homemade plum gin. But as glasses of the tangy tipple are quaffed, disaster strikes! Chairwoman of the village show, Alice Warren, slumps to the ground - poisoned! As fingers of suspicion again point Martha's way, she's determined to prove her innocence and find the real culprit. And she's ably helped by the new vicar, Luke Walker. But who would kill Alice and why? And will Luke and Martha discover who is behind the poisoning before it's too late?
