Story without spoilers

Harry Kettle is a television gardener who arrives to work on a client’s garden. What initially appears to be a normal job soon changes when he discovers that the residents are extraterrestrial beings rather than ordinary people. They are described as evil aliens from another planet, and Harry must defeat them before it is too late.

The supplied story information keeps the focus on the central threat without revealing how Harry responds, what the aliens are planning in detail, or how the conflict ends. The film’s tagline captures the basic contrast: Harry comes to trim hedges, while his clients arrive with ambitions to conquer Earth.
