Species II

Three years after the events of the previous film, Commander Patrick Ross leads a manned mission to Mars. Soil samples collected by Patrick's team of astronauts contain a substance which thaws aboard their capsule and attacks them, causing a seven-minute contact gap with mission control. With seemingly no subsequent negative effects, the astronauts return to Earth to public celebration. However, an institutionalized former scientist, Dr. Cromwell, reacts to their return with violent panic. Meanwhile, Dr. Laura Baker has created a clone of Sil named Eve, whose alien DNA is suppressed to make her more docile. Her team conducts experiments on Eve, hoping to find a way to combat the alien species should it ever return to Earth. Every experiment is unsuccessful as Eve's biology adapts.

Upon their return, Patrick and his team are told to refrain from sexual activity for ten days. Patrick disregards this advice and has a threesome with two sisters following a fundraiser. During intercourse with the second woman, he begins to sprout tentacles. The woman notices his transformation while she is stroking his body and is horrified at the sight of him where she tries to free herself from his clutches. Both women endure accelerated pregnancies, ending with Patrick's half-alien children tearing out of their abdomens. Patrick hides both corpses and his rapidly growing sons on the property of his father, U.S. Senator Judson Ross. The next day, Patrick tells his father he cannot remember the previous night's events. Senator Ross indicates that he is aware of Patrick's behavior and tells him to focus on his political goals.
