NileCity 105.6 is a story about Percy Nilegård who has ventured into the commercial radio business. The radio station rents premises of the fire station, where the self-willed chief Greger is in charge of six well-built firemen.
Each episode features a presentation of one of the firemen, showcasing their special and relaxed relationship with each other. Percy is always on the lookout for money, using unconventional methods to attract sponsors.
The main radio host, Glenn Killing, interacts with various (and often peculiar) guests on the show. There are also other programs like a reggae show, a Friday party program, a teenage psychologist (and stereo fetishist) named Farbror Barbro, and Percy's own "Management Profile".
