In an untraversed desert, the only source of water and an oasis is built as a beautiful town named Q-Town. The city has complete equipment and a group of happy and carefree residents under the Q-Star League's protection. Flame, the captain of the Q-Star League, is enthusiastic and persevering. Brave Thunder, narcissistic and elegant Shine, shy Iron, and base camp correspondent Florrie are the members of it. They have different personalities and hobbies, but when it comes to the problem of Q-Town residents, they work together to maintain the town's public security. Q-Star League is deeply loved by the residents, and even Thunder's younger brother Flash is eager to be one of the team members.

The peaceful life of Q-Town is broken by a group of crashers – the Buster Gang: Cyclone, Phantom, and Snap. The gang sneaks into the town and tends to collect things such as machine parts, water, electricity, etc. Q-Star League will always stop Buster Gang from destroying the city. In this process, members of the Q-Star League help each other, improve themselves, and overcome their weaknesses; their friendship becomes solid.

After several confrontations with Buster Gang, Q-Star League discovers the hidden truth behind Buster Gang's strange behaviors. They collect resources in Q-Town to repair their airship so they can return to their planet. At the end of the story, members of the Q-Star League decide to forgive whatever Buster Gang did and help them return to their hometown. Q-Town returns to be peaceful after that.
