The few habitable planets encountered are ultimately abandoned either because they are already occupied (emphasizing the wrongdoing of invading other civilizations and cultures), or because upon closer inspection they are found to have other problems, such as cow-sized mosquitoes, high radiation levels, dog overpopulation, unsuitable living environment, and other issues.
Using the classic sitcom style, the characters' interactions drive the main plot in the same recurring spaceship sets (the bridge, dormitories, medical room, hallways).
The satirical humor of the show is heightened by playing on the fact that the characters themselves recognize the farfetchedness of the universe in which they live and much of the series' comic relief is derived from the look and feel of low-budget set (an alien is obviously a human only painted green, gadgets are recognizable objects, etc.).
A lot of the comedy is also based on the group's dynamics and reactions to certain events, such as the entire crew turning their heads in the same direction every time the captain says the word "mission".
The starship, christened Romano Fafard, is led by Captain Charles Patenaude (played by Guy Jodoin), a presumptuous but endearing man prone to making pompous, solemn declarations, with a knack for screwing up when saying proverbs or quoting philosophers.
Other members include: Flavien Bouchard (Claude Legault), the radar operator who possesses heightened senses and is in desperate search for his father (it is learned in the last season that his dad is an alien), Bob Dieudonné Marcellin (Didier Lucien), a bald, black chubby man who is the spaceship pilot (the spaceship's dashboard is a bus dashboard, complete with steering wheel) who is best friends with Flavien and who obsesses over two things: food and Petrolia Staneslavsky (Mélanie Ménard).
Serge (Réal Bossé) is a humanoid robot Petrolia created, stricken with multiple personalities and abilities and who is constantly falling into disrepair.
The series is a parody of science-fiction works like Star Trek or Red Dwarf and often dealt with environmentalism, humanitarianism, pacifism and ethics.
