Tail Sting (2001)

The movie begins with a massive earthquake hitting the city of Los Angeles. Amidst the chaos and destruction, a cargo plane carrying a rare and dangerous species of wasps, called the "reckoners," crashes into a building. The reckoners manage to escape and make their way into the city.

Meanwhile, a group of survivors take refuge in an underground subway station with limited supplies. Among them are Mike, a former military pilot, and Claire, a young woman with a passion for insects. As tensions rise while they await rescue, the reckoners start attacking other survivors, injecting them with their venomous sting. The venom mutates the victims, turning them into giant and aggressive humanoid wasp creatures.

Mike, Claire, and a few others realise the threat posed by the reckoners and form a plan to escape the subway station. Armed with makeshift weapons, they fight their way through the mutated creatures and make their way to the surface.

Outside, the city is in ruins, with mutated wasp creatures terrorizing the remaining survivors. Mike and Claire join forces with a group of military personnel who have managed to set up a temporary base in a nearby hospital. The military informs them that the reckoners are attracted to a particular kind of pheromone and are, therefore, drawn to populated areas.

Determined to stop the infestation and save the city, Mike and Claire volunteer to find the reckoners' nest and destroy it. With the military's assistance, they navigate through the devastation, encountering swarms of mutated wasps along the way.

Eventually, they locate the reckoners' nest within a damaged skyscraper. Armed with specialized equipment, they enter the nest and engage in a fierce battle with the queen reckoners. Despite being outnumbered and facing overwhelming odds, they manage to defeat the queen reckoners and destroy the nest.

With the nest destroyed, the surviving reckoners lose their cohesion and disperse throughout the city. The military starts an extensive extermination operation to eliminate any remaining reckoners.

In the aftermath, the survivors unite to rebuild the ruined city, remembering the sacrifice made by those who fought to protect them. Mike and Claire develop a deep bond throughout their ordeal and decide to stay together in the new world they helped to save.
