I'll narrate the story of Venom (2018) in a detailed, linear fashion:

The story begins with Eddie Brock, an investigative journalist in San Francisco, who is known for his hard-hitting exposés. He's in a relationship with Anne Weying, a successful lawyer. During an interview assignment about the Life Foundation, led by Carlton Drake, Eddie becomes overly aggressive and asks pointed questions about unethical scientific experiments, which ultimately costs him his job and causes Anne to break up with him.

Carlton Drake, a brilliant but ruthless scientist, has been conducting experiments with alien symbiotes - living organisms that require a host to survive. These symbiotes were brought back from a space mission, and Drake is desperately trying to find compatible human hosts, conducting dangerous trials that result in multiple human deaths.

Eddie, driven by curiosity and a sense of journalistic integrity, breaks into the Life Foundation laboratory. While investigating, he accidentally becomes infected with a symbiote named Venom. Immediately, he begins experiencing strange physical changes and hearing a voice in his head. The symbiote communicates with him, revealing its alien nature and its ability to merge with and transform its human host.

As Eddie struggles to understand what's happening to him, he discovers that the symbiote provides him with extraordinary abilities - superhuman strength, rapid healing, and the capacity to shape his body into weapons. Venom explains that it comes from a planet where symbiotes are common, and it has been separated from its original group.

Meanwhile, another symbiote named Riot is seeking a more powerful host. Riot moves from body to body, ultimately choosing Carlton Drake as its preferred host. The symbiote's goal is to bring more of its kind to Earth and colonize the planet.

Eddie must learn to coexist with Venom, navigating the complex relationship between human and symbiote. Their interactions are initially antagonistic but gradually become more cooperative and even humorous. Venom helps Eddie fight against Drake and Riot, using their combined abilities.

The climax occurs in San Francisco, where Drake/Riot attempts to bring a symbiote invasion ship to Earth. Eddie and Venom must work together to stop this invasion. In an epic battle, they confront Riot, ultimately defeating the more aggressive symbiote and preventing the alien invasion.

By the end of the film, Eddie and Venom have formed a unique partnership. Eddie learns to accept the symbiote, and Venom develops a sense of protection towards Eddie and humanity. They decide to work together, with Venom helping Eddie investigate wrongdoings while using their combined abilities.

The movie ends with a hint of future adventures, showing that Eddie and Venom have become an unconventional but effective team, ready to take on new challenges.

The narrative is marked by dark humor, action sequences, and an exploration of the symbiotic relationship between a human and an alien organism, creating a unique superhero origin story.

At the end of the movie "Venom," Eddie Brock and Venom defeat the villain Riot, preventing him from taking over Earth and saving the planet from destruction. Eddie accepts his bond with Venom, realizing they can work together as a team, and he decides to embrace his dual identity rather than fear it.

In a more detailed narrative, as the climax of the film unfolds, Eddie Brock and Venom face off against Riot, the more powerful symbiote that has been causing havoc and seeks to bring other symbiotes to Earth. The final battle takes place at the Life Foundation, where Riot plans to launch a rocket to bring more symbiotes to the planet. Eddie, after coming to terms with his relationship with Venom, taps into his newfound confidence and strength. Together, they fight Riot in a fierce battle, displaying both their individual skills and their symbiotic bond.

In a tense moment, Eddie is nearly defeated, but Venom motivates him to fight back, pushing the boundaries of their partnership. Ultimately, they manage to eliminate Riot, leading to a moment of realization for Eddie: instead of viewing Venom as a curse, he sees the potential of their partnership. By the end of the movie, Eddie embraces his dual identity with Venom as they share a bond that is both complex and beneficial to both of them.

The film concludes with Eddie and Venom taking on a new purpose: they decide to fight against wrongdoings and protect the innocent, setting up a dynamic where they can use their combined strengths for good.

Significantly, the ending underscores themes of identity and acceptance. Eddie's journey highlights the struggle of embracing the parts of oneself that may initially seem alien or unwelcomed. Instead of viewing the symbiote as merely a threat, he learns that by accepting this other side of himself--Venom--he can achieve greater strength and purpose. The film leaves viewers with a message about the power of partnerships and the importance of embracing one's complexities.
