DEEP SPACE

A team working on a U.S.military satellite program under the direction of head scientist Forsythe loses control of a precious satellite. They realize that they can not prevent its crash on earth within the next two hours. Upon impact, the satellite breaks open, but its contents remain inert. Forsythe informs the officer in charge, General Randolph, of the situation. The satellite contains a biological weapon of a whole new genre, an actual sentient creature nicknamed "Sentar". Randolph wants the beast destroyed via its remote emergency system, but Forsythe is reluctant and minimizes the risks, arguing that there is little risk that it will wake up. However, a couple passing by disturbs the creature's sleep, and get killed after setting it loose.

The monster escapes towards Los Angeles and begins to terrorize the citizens. Meanwhile, veteran police lieutenant Ian McLemore is introduced to a newly transferred colleague from Atlanta, Carla Sandbourn, with whom he sympathizes. Their superior, Captain Robertson, attempts to dissuade Sandbourn from working with McLemore, as the latter has the reputation of getting involved in dangerous situations from which he always seems to come out unscathed, while his partners seldom live to tell the tale. McLemore is informed of an incoming call from a woman who claims to be a psychic and needs to talk to him, but refuses to take it. Instead he leaves for Innsmouth Road, where a double homicide scene has been discovered, with his regular partner Jerry Merris. There, they find a large pod that seems to be made of a hard, yet organic material, as well as several similar but smaller objects.

McLemore insists that he and Jerry steal two of the smaller pods and take them home to investigate further, as he fears a cover-up is afoot. Meanwhile the large one is taken to the local forensics lab, but during the night, the examiner, Rogers, is hacked to pieces by an unknown force. Testing also reveals that fragments of an unknown metal retrieved from the crime scene do not match any known material. When they attempt to return to the crime scene, McLemore and Merris are barred from entering by Military Police members, led by a mysterious suit who points his gun at them. Later, they see the same man exiting Robertson's office, who soon after informs them that the deaths have been ruled accidental, despite blatant evidence of the contrary. Back at his home, McLemore receives another call from the psychic who had earlier tried to contact him at the police station. The woman, named Lady Elaine Wentworth, claims to know what happened the previous night.

Sanbourn joins McLemore and they enjoy a date. McLemore remembers his pod and the two go to an entomologist that McLemore knew from a previous encounter, taking the pod. The pod is drilled open and hatches, with the creature inside attacking the entomologist and Sanbourn. The creature is destroyed in a terrarium filled with a gas. After the entomologist is wheeled away by the paramedics, McLemore recalls Merris' pod. He and Sanbourn go to Merris' home, to find that the pod has hatched and Merris has been killed. A chase ensues and the second creature is finally killed.

Lady Elaine calls Merris' home to tell McLemore where the original creature is. McLemore and Sandbourn find the location, and Sanbourn calls for backup. The creature eventually fights McLemore, and is winning until Sanbourn and Robertson, who has just arrived, attack. The distraction allows McLemore to decapitate the creature with a chainsaw.
