The 5th Wave (2016) is a sci-fi thriller based on Rick Yancey’s novel. The film follows Cassie Sullivan (Chloë Grace Moretz), a teenager struggling to survive after Earth is attacked by extraterrestrials known as “The Others.” The invasion unfolds in devastating “waves”: an electromagnetic pulse, natural disasters, a deadly virus, and human infiltration. Separated from her younger brother, Cassie embarks on a perilous journey to rescue him, encountering a mysterious young man, Evan Walker (Alex Roe), who may not be entirely human.
Meanwhile, her childhood crush, Ben Parish (Nick Robinson), is recruited into a military resistance force. As Cassie uncovers shocking truths about the supposed human defenders, she realizes that the fifth wave is already in motion—a sinister plan to turn humans against each other. Racing against time, she must rely on her instincts to save her brother and fight for humanity’s survival.
