Martha Kearney's year gets off to a bad start when unseasonal snow in spring threatens to kill the bee colonies she keeps in her garden in Suffolk. With help from a master beekeeper Martha feeds her bees and takes one of the hives to a wildflower meadow at a neighbour's house along with two brand new hives. She discovers the intricate hierarchy within the bee colony and learns how the organisation of the hive has become a metaphor for human society. At a London school she learns the secrets of urban bees' success even while bees in the country as a whole are in decline. The episode ends with three new hives established on a wildflower meadow, ready to start producing classic British wildflower honey.
