Field Commander Uljabaan's loyalty cards, rewarding villagers for their collaboration, are not only ruining Katrina's plans but also Richard's chances in the weekly pub quiz.
They turn to Ron, the landlord of the Rose & Crown for help in scuppering the scheme.
Eddie Robson's sitcom about aliens invading the village of Cresdon Green.
Starring Hattie Morahan and Peter Davison.
Noticing all-at-once invasions of Earth never work out too well, these aliens have locked villagers behind an impenetrable force-field in order to study human behaviour and to decide if Earth is worth invading.
The only inhabitant who seems to be bothered by their new alien overlord is Katrina Lyons, who was only home for a weekend to borrow the deposit for a flat.
So along with Lucy Alexander (the only teenager in the village, willing to rebel against whatever you've got) she formed The Resistance - slightly to the annoyance of her parents Margaret and Richard.
This is also much to the annoyance of Field Commander Uljabaan who, alongside his unintelligible minions and The Computer (his hyper-intelligent supercomputer), is trying to actually run the alien invasion.
