Alien³ (1992) is the third installment in the Alien franchise, directed by David Fincher in his feature film debut. The film stars Sigourney Weaver reprising her role as Ellen Ripley, the sole survivor of the previous two films, Alien (1979) and Aliens (1986).

The story begins with Ripley’s escape pod crash-landing on Fiorina 161, a remote, desolate prison planet inhabited by male prisoners with violent pasts. Stranded on this dangerous world, Ripley discovers that the xenomorph, the deadly alien species she has been battling, has followed her to the prison.

With no weapons and limited technology, the prisoners and Ripley must work together to stop the new alien threat that begins hunting them one by one.

As the film progresses, Ripley faces a shocking personal discovery—she is carrying a xenomorph queen embryo within her, making her both the ultimate target of the alien and the key to its survival. In a final act of heroism, Ripley must confront both the alien and her fate to protect humanity from the deadly creature.

Alien³ is known for its darker, more somber tone compared to its predecessors and features themes of isolation, sacrifice, and mortality.

Although initially divisive among fans and critics due to its bleak storyline and departure from the action-heavy approach of Aliens, the film has since gained appreciation for its atmospheric direction, haunting score, and unique take on the Alien saga.
