V1, also known as V1 Murder Case, is a 2019 Tamil suspense thriller film directed by Pavel Navageethan in his directorial debut.

The movie follows Inspector Agni (Ram Arun Castro), a forensic expert who is undergoing treatment for nyctophobia and is suffering from hallucinations about a past murder.

His colleague, Inspector Luna (Vishnupriya Pillai), convinces him to take the case of a recently murdered young woman.

The duo interrogate the victim's boyfriend Inba (Lijeesh), who admits that he and Narmadha (Gayathri) had been going through a rough patch while living together.

Finally, he discovers that Narmadha's father killed her by stabbing her neck with a pen as revenge for her relationship with a lower-caste man.
