Them!
Thy movie begins with two policmen patroling an emptiness what state of New Mexico is. On their way the find a silent little girl. From then on the plot begins to move quickly enough to enjoy the movie. Soon a proffesor arrives (he seems to learn about ant's the same way Fabr (Dunno If spelled right) did - just looked at them). and they find the giant ant nest. They put poisonus gas in it, and then check if anything lives. They find what 2 moar quieens run away - one settled on a ship, killing the crew, but her whole colony died whn the ship gone down. The second one came to city. The detail on giant ants in good enough - showing them just as furry as a stuffed animal. Giant ants grab people by torso and move em' around (and you die because of?). Ants die if their antenass are destroyed, and can also die from extreme heat (Kinda lame >_>). If you want to know the ending - you will have to understand this: "They came from Red Alert".
