What it's about: This experimental satire is a comedy of ideas about an alien in the city, who asks questions that no one has asked before. They are innocent, child-like questions, but they bring about catastrophic answers. People who are set in their ways for generations, are forced to reappraise their world when they see it from PK's innocent eyes. In the process PK makes loyal friends and powerful foes, mends broken lives and angers the establishment. PK's childlike curiosity transforms into a spiritual odyssey for him and millions of others. This offbeat, experimental drama is an ambitious and uniquely original exploration of complex philosophies. It is also a simple and humane tale of love, laughter and letting-go. Finally, it is a moving saga about a friendship between strangers from worlds apart.

What it's about: Many people think of Space as a quiet and desolate vacuum of emptiness, but new evidence reveals that space is rife with activity beyond our comprehension. Just as we sent Voyager and Pioneer probes beyond our solar system, Aliens have probes of their own that may have arrived as early as the 1600's. While Tesla was the first to successfully communicate with neighboring worlds using radio waves, we have received recent signals from intelligent sources. In 1989, Russian Space Probe Phobos 2 photographed a UFO on the surface of Mars just prior to losing contact. Scientists have determined that the craft was real and of a thin elliptical shape over 20 miles in length. We are not alone in outer space and while the Aliens may be initiating contact, they could also be here already.
