The Swarm
Killer bees from South America have been breeding with the gentler bees of more northern climates, slowly extending their territory northward decade after decade. Entomologist Brad Crane has discovered that something is making them come together in huge, killer swarms. He wants to keep General Slater from using military tactics from further upsetting the balance of nature as they join to try to stop the swarms from approaching Houston, Texas.
The film commercial failure against its respectable budget of $21.0M, earning $7.7M globally (-63% loss). While initial box office returns were modest, the film has gained appreciation for its compelling narrative within the horror genre.
