Delta and the Bannermen is the third serial of the 24th season of the British science fiction television series Doctor Who, which was first broadcast in three weekly parts from 2 to 16 November 1987.
In the serial, aliens called the Bannermen track down the Chimeron Queen Delta (Belinda Mayne) to a Welsh holiday camp in 1959 so they can kill her.
She reaches a space tollport where the Navarinos, a race of shape-changing tourist aliens, are planning a visit to Disneyland on the planet Earth in 1959, in a spaceship disguised as an old holiday bus.
A battle ensues with Gavrok and his Bannermen against the Doctor and his crew: Ray & Billy, Goronwy, Mr. Burton and the two CIA agents.
Goronwy explains to Billy the purpose of royal jelly in the lifecycle of the honeybee, provoking the mechanic to consume Delta's equivalent that she has been feeding her daughter, in the hope of metamorphosing into a Chimeron.
Delta and Billy leave together with the child, the two agents watch on with surprise and Goronwy winks knowingly as the Doctor and Mel slip away.
