Farmer Geraldine Merrick suspects vandalism when crop circles appear in her wheatfield. She plans to harvest immediately but widowed ufologist Terry is convinced it is the work of aliens and a site of scientific interest and requests Peter to stop her. Geraldine calms down when sci-fi fans pay to camp in her field but Peter suspects that Terry's neglected young son and Terry's rivals in the pub quiz know more than they claim. Lyle wins the day for an eccentric old couple whose sour-faced daughter feels they should be put in a home, thanks to an eccentric judge, but finds himself falling for rival solicitor Emily.
