We join the Baldock Allotment Growers inside their clubhouse/potting shed as they prepare for the annual flower and produce show. Bob is relying upon Alex, a local councillor, to agree planning permission for a make-or-break building project. Alex is desperate to steal gold from Bob in the root vegetable category, having already stolen Bob’s wife. Alice, on work experience from horticultural college, observes quietly, waiting for the right moment to reveal her true identity. Rachel, Alex’s wife, is in charge of judging, along with Inspector Harry Hart, who also shares a dark secret with Alex.
