If you mean the Off the Grid season shown in that picture, it’s about Striker, Pixel, Raptus, Shift, Clint, and Regalius and the conflict between the protected GRID and the dangerous world outside it.

The main storyline starts with Pixel being captured, which sends Sheriff Striker on a mission to rescue her. He teams up with his old friend Raptus and engineer Shift, leaving the GRID despite Regalius trying to keep him inside.

The bigger story involves:

• Striker & Pixel: Striker is trying to find and rescue Pixel after her capture.

• Raptus & Shift: They help Striker travel beyond the GRID.

• Regalius: The leader of the GRID, who wants to maintain control and keep the outside world away.

• The Outlands: A dangerous area beyond the GRID with rival factions and threats.

• Later seasons expand into the Nightmare Realm, where Striker and Shift become trapped and Pixel searches for a way to reach them.

So basically: a rescue mission turns into a much bigger conflict over the GRID, the Outlands, and who controls them.
