The plot centers on Captain Ranveer "Ronnie" Pratap Singh (Shroff), who investigates the kidnapping of his ex-girlfriend Neha's (Patani) daughter, Rhea. Facing opposition from authorities, Ronnie uncovers a drug-related conspiracy, ultimately discovering Rhea is his biological daughter and rescuing her.

The characters in Baaghi 2 are well-developed and complex. Ronny, the protagonist, is a brooding and angry young man who seeks justice. His character arc is well-defined, as he transitions from a revenge-seeking individual to someone who understands the value of relationships and forgiveness. Shraddha Arya's character, Pooja (Ron's love interest), adds depth to the story, and her chemistry with Tiger Shroff is undeniable. The supporting characters, including Vijay (Sachin Khot) and Ali, are well-etched and play important roles in the narrative.

Ronnie, an Indian Army officer, is contacted by his ex-girlfriend Neha, whose three-year-old daughter, Rhea, has been mysteriously kidnapped. As Ronnie investigates in Goa, he encounters conflicting reports from Neha's husband and neighbors who claim the child never existed, leading him into a complex web of crime and drug cartels.
