Plot
Paul works as a waiter for Julia who runs a catering company. They go to set up for a function at the Perch estate. The rural world of Mrs. Perch, a well-to-do elderly lady in New York, is all abuzz in anticipation of her annual garden party, a small but elaborate affair held in a villa at the remote estate where she resides with her son Sydney. Among the guests is the town mayor, Caruthers.
Unfortunately, thanks to an illegally imported plant fertilizer mixed with growth hormones which seeps into the ground, a local species of parasitic wasp mutates into significantly larger creatures. Mrs. Perch's upper-class celebrants, slowed by the evening's festivities, are the ideal prey. The wasps burrow inside the bodies of the guests to emerge as creatures seven feet long.
Paul and Julia have to try and figure out how to stop the giant wasps. They realize that the wasps reproduce through their stingers, also ovipositors, as juvenile wasps emerge from human hosts who are killed in the process.
