The bee-yard at a Devonshire monastery looks deceptively serene on a summer day. No one expects greed and violence to spoil the peace where an old monk prepares to leave a famous legacy by breeding the perfect brood of honeybees (gentle and productive). Eleven-year-old Joe is sent to help Brother Adam, the beekeeper, as an act of penance. The abbot caught him helping a gang steal from the monastery orchard. He has more to contend with than the grouchy monk and stinging insects. His older cousin, Emily, from London visits for the holidays following his father's death. She joins him with the monk in the bee-yard but is distracted by a village rumor about medieval monks hiding treasure on the grounds of the former abbey. She dreams of writing about the discovery for a debut as a junior novelist.

On returning home she finds the hive threatened by a monster previously only imagined by bees in their mythology. She allies with Hemlock to drive it off and saves the hive before looking for her family.The keepers discover the tragedy of a vandalized hive during their tea party in the monastery garden. Then, the monk explains how to find a swarm by tracking a scout bee. When Sundew feeds from a bowl of honey on the table, Joe recognizes it as the bee he saved from the sundew while walking with Emily. He follows her beeline to recover the swarm and helps the monk reinstall it in the hive. Only he knows the attack on the hive won't be the last. Greedy hands are seeking the legendary treasure.
