The Owls have arrived on our beautiful blue planet, alien invaders with many tentacles instead of legs. They have been wandering through intergalactic space looking for a new planet on which they could live in peace and perhaps even tranquility.

Their original home was destroyed by the hostile Gorgos, who for some reason got angry with them and are chasing them across the universe. However, this is not the beginning of a movie about the War of the Worlds, but of the magical and funny animated comedy Home at Last.

The alien invasion of the Buvas on Earth is quite benign and kind - the Buvas begin to remake their new home in their own image and start by simply moving people to Australia, where they give them a very comfortable life thanks to their advanced Buvan technology. However, during this move, a girl named Tipy slips through their fingers, who has been looking for her mother ever since. Tipy has a very adventurous nature and a cat named Piglet. Why not, right?

A little purple-haired, talkative, and very friendly Buvan named O has also found his little home on Earth. That's why he immediately starts preparing a party to which he invites everyone and accidentally sends an intergalactic invitation to the Gorgas.

Which is a really big mess, making the other Buvas very angry with him and some of them want to say a few words to him. O takes all his tentacles on his shoulders and needs to hide somewhere for a while until their heads cool down a bit. On the run, O comes across the lost Tipsy and gradually an intergalactic friendship develops between them.

O tries in his own cute way to fix everything the Buvans have caused by their arrival on Earth, causing chaos at the speed of light. In return, Tipsy introduces Oa to humor, art, music and dance, family and friendship. But most of all, Oh and Tipsy try to understand each other and find Tipy's mom.
