Q plot
"Its name is Quetzalcoatl. Just call it Q. That's all you'll have time to say before it tears you apart!"
The police don't believe the rumors that a huge flying lizard is circling over the city. Unfortunately, victims soon fall and the entire police force seems to be unable to do anything about it. However, an unemployed piano tuner accidentally discovers the monster's nest and devises a plan to defeat the beast.
