In The Aatronauts, the spacecraft Odyssey II is set to launch on a mission to retrieve a foreign object that could potentially save mankind. The plan quickly goes awry when five untrained kids use their parents’ security clearances to sneak onto the empty ship. Soon after they board, the onboard AI system triggers the launch sequence. Unable to stop the ship from blasting off, the kids must assume their new role as astronauts and brave harrowing tasks, as their parents rush to find a way to take control of the situation.
