Two royal extraterrestrial siblings, Princess Aja and Prince Krel of House Tarron, their doglike pet named Luug, and their bodyguard, Varvatos Vex, escape from their home planet of Akiridion-5 and crash-land on Earth, specifically in the California city of Arcadia Oaks. There, the aliens adjust to human culture and try to fix their spaceship (as well as to restore their nearly-dead parents King Fialkov and Queen Coranda) to return and take back Akiridion-5, which is being taken over by an evil dictator known as General Val Morando, who has already sent out a team of intergalactic bounty hunters, called the Zeron Brotherhood, to find and catch the prince and princess. After investigating a way to stop Val Morando and find the hiding place of Aja and Krel, Zadra, one of the noble protectors of the royals from Akiridion-5, arrives on Earth. Meanwhile, after learning of his involvement in Morando's coup, Aja and Krel decide to exile Vex. During his exile, Vex is captured by the Zeron Brotherhood and imprisoned at a bounty hunter outpost located on Earth's moon. In Season 2, Aja and Krel learn of his capture and launch a rescue mission. Soon after the rescue, however the gang discovers that Morando is heading for Earth. After successfully defeating him, Aja, Vex, Zadra, Luug and the rest finally return home, joined by Eli, who has volunteered to be Earth's ambassador on Akiridion-5. Krel decides that Earth has become his home, and decides to stay with his new human friends.
