Zane Zaminski (Charlie Sheen), a radio astronomer working for SETI, discovers an extraterrestrial radio signal from Wolf 336, a star 14 light years from Earth. Zane reports this to his supervisor, Phil Gordian (Ron Silver) at the Jet Propulsion Laboratory, but Phil dismisses the claims. Zane soon finds that he has been fired because of supposed budget cuts, and blacklisted, preventing him from working at other telescopes. Taking a job as a television satellite installer, he creates his own telescope array using his customers' dishes in the neighborhood, operating it secretly from his attic with help of his young next door neighbor, Kiki.Zane relocates the signal, but it is drowned out by a terrestrial signal from a Mexican radio station. Zane attempts to tell his former coworker, Calvin (Richard Schiff), but finds he has just died suspiciously from carbon monoxide poisoning. Zane travels to Mexico and finds the radio station was burnt to the ground. Searching the local area, he comes across a new power plant. There, he helps climatologist Ilana Green (Lindsay Crouse) protect her atmospheric analysis equipment from the plant's overzealous security forces. Ilana explains that the Earth's temperature has recently risen several degrees, melting the polar ice. She is investigating the power plant, one of several recently built, that appears to be the cause of this increase. The two are released, but without Ilana's equipment. Surprisingly, Zane realizes one of the guards could pass as the identical twin of his former boss, Phil, except that he is of Mexican ethnicity (whereas Phil is not). As Zane and Ilana regroup, Phil instructs some agents, posing as gardeners, to release an alien device in Zane's attic that creates a miniature black hole, consuming all of Zane's equipment. Zane leaves Ilana to again investigate the power plant and she is soon killed by a scorpion planted in her room.Zane discovers the plant is a front for an underground alien base. The very different looking aliens are able to disguise themselves with an external skin to infiltrate our society. Zane finds that all of the bases expel large amounts of emissions into the atmosphere. Zane is discovered but escapes back into the nearby town and attempts to convince the local sheriff of the situation. However, alien agents bring Ilana's body to the police station, making Zane a suspect in her death; Zane escapes and sneaks back into the United States. He accosts Phil on the JPL grounds, forcing him to admit that the aliens are trying to raise the Earth's temperature to not only kill off humans but make the planet hospitable for themselves. Zane secretly records the conversation and once Phil discovers the recording he sends agents to stop Zane.Zane returns home to find his attic devoid of equipment. He figures out the only way to broadcast the tape is to go to a nearby telescope and beam the signal directly to a television satellite, broadcasting it worldwide. With the help of his girlfriend Char (Teri Polo) and Kiki, he travels to the telescope. Phil and his agents soon disable the telescope controls from the main building. Zane leaves the tape with Kiki and instructs him to transmit it when he gives the order and then he and Char sneak over to the telescope's base and barricade themselves in the control room. Zane makes the necessary adjustments and tells Kiki to active the tape, but Kiki reveals himself to be an alien agent, and opens the door to allow Phil inside and confiscate the tape himself.Phil and his agents ram down the door to the telescope room with a van, but Zane freezes them with cryogenic gases. As he works to free the tape stuck in Phil's frozen jacket, one of the agents drops a sphere which starts to form another singularity in the room. Zane and Char escape through the telescope's optical path before the device implodes most of the telescope base, exiting safely onto on the collapsed dish. In the distance they see Kiki, and Zane tells him to tell the aliens that he will soon broadcast this tape; they watch as Kiki runs off. In the film's epilogue, Zane's conversation with Phil is broadcasted across the globe
Output: After being fired, where does Zane secretly work from with this homemade telescopes?
