Noted British horror director Freddie Francis and author Robert Bloch, who wrote , combined their talents for this tale of terror. Pop singer Vicki Robbins (Suzanna Leigh) collapses from exhaustion and takes a vacation on a small resort island. She soon meets Mr. Hargrove (Guy Doleman), a difficult man with a failing marriage who owns the resort and keeps bees as a hobby. Charming Manfred (Frank Finlay), who also lives on the island, keeps bees as well, and he soon strikes up a friendship with Vicki. However, when first a dog and then Hargrove's wife are killed by bee stings, Vicki discovers that someone on the island is breeding a strain of killer bees, and she has to find out who is responsible and what can be done before they kill again. Keep an eye peeled for a short appearance by the British beat combo The Birds, whose guitarist, Ron Wood, would later become a star playing with The Faces (featuring Rod Stewart) and The Rolling Stones.
