The trilogy follows a 19-year-old girl named Rey, and the plight of the Resistance against the First Order, which has risen from the fallen Galactic Empire. Rey learns the ways of the Force under Luke Skywalker and Leia Organa while searching for her parents (who mysteriously abandoned her as a child), and confronts Kylo Ren—the son of Leia and Han Solo, nephew of Luke, and grandson of Anakin Skywalker—who has fallen to the dark side. The first two received positive reviews from critics, while the third received mixed reviews. The trilogy grossed over $4.4 billion at the box office worldwide with each film surpassing a billion dollars worldwide.
