Alien 3 begins with Lieutenant Ripley (Sigourney Weaver) crash-landing on a desolate planet used as a penal colony. The criminals housed there are led by Dillon (Charles Dutton). They have adopted a vow of celibacy and a millennial religion. This makes them quite unfriendly. A sensitive physician (Charles Dance) offers Ripley some solace but that all vanishes once she realizes an alien has come with her to the compound. When she learns that there are no weapons on the planet, she knows that only her brain and her courage can fight the monster. Alien 3 works well enough as a thriller, and Sigourney Weaver is winning once again as a tough woman warrior.
