Binky the Space Cat along with fellow space pets Gordie and Gracie have been left at the pet hotel while their humans go on holiday. Only it's not a hotel at all - it's the vet! 'No way are they staying,' Binky thinks. 'They are an elite space team. There is no chance that a 'pet hotel' will contain the likes of them.' So the trio hatch a plan to escape through the building's vents. But along the way, their mission takes a precarious turn when they stumble upon the secret lab of the notorious Professor Tuffy in the vet's basement.
