When a lighthouse keeper reports seeing a ball of light plunging into the sea off Tayborough Sands, UNIT sends Mike Yates to investigate. He is surprised to bump into an old friend, the Doctor, who has brought his friends Tegan and Turlough there for a holiday -- a holiday which is short-lived after the crew of the boat Papillon are discovered slaughtered.
