Okay, here is a description of the ending of Alien: Resurrection (Alien 4: Resurrection):
The film concludes with Ripley (played by Sigourney Weaver) having successfully completed her mission: the alien queen has been impregnated with human DNA and is about to lay a clutch of hybrid eggs. She defeats the main antagonist, android David, who is revealed to be the "perfect host" for the aliens.
As the queen lays the eggs, Ripley, now heavily pregnant with alien/hybrid offspring, stabs the queen in the eye with a dart gun, killing her. However, before dying, the queen impales Ripley through the chest with a tail spine, fertilizing her instantly.
The final scene shows Ripley lying on the metallic floor of the derelict space station (Acheron). She is surrounded by hundreds of rapidly developing alien/hybrid facehuggers, having become the incubator for the new species. She looks directly into the camera, her expression one of serene peace, as if she has found a form of transcendence or final release, becoming one with the alien life she has both fought against and孕育ed (yù yǎng nurtured/gave birth to).
The film ends ambiguously, leaving the audience uncertain about Ripley's fate – will she survive the hatching, transform, or die, but reach a strange form of apotheosis? The final shot of her peaceful expression is heavily interpreted as suggesting she has found a new purpose or existence within the alien life cycle.
