The movie is set in Visakhapatnam, a bustling port city on India's east coast known for its beaches and industry. The coastal urban setting provides a gritty, real-world backdrop for the detective story, with locations ranging from a businessman’s house to local jewellers.

The film centers on defining true lineage and belonging within a fractured family. The search for the missing brother exposes how society ostracizes children of illicit unions and questions what makes someone a rightful heir. Blood tests and family secrets become tools as the protagonist navigates loyalty and truth.

Pandu's romance with Jwala begins as friendship and faces doubt from peers. As the case unfolds, trust grows between them and their bond becomes a personal stake in the investigation. Their relationship provides emotional motivation that grounds the detective's quest for justice.

The plot pits official power against clever subterfuge as the villain's crimes are unmasked. The unofficial investigation, aided by police collaboration, exposes deceit and leads to arrest. The film stresses that truth and fair play can prevail, even if the system is not perfect.

Panduranga Rao, nicknamed Pandu, is an amateur detective at Universal Detective Agency who idolizes James Bond and mimics his look and bravado. He is routinely dismissed by police and colleagues, yet his persistence gradually uncovers the truth. His eccentric methods and determination drive the investigation.

Jwala is a self-employed telephone cleaner whose friendship with Pandu becomes romantic. She is skeptical of Pandu's detective skills at first, but her trust deepens as the case progresses. She is initially implicated in the murder but is cleared as Pandu uncovers the truth and protects her.

Murthy is a detective appointed by the police to assist with the case, who is later revealed to be the mastermind behind the crime. He confesses his crimes during a covert confrontation with a jeweller and is ultimately unmasked by the protagonist and police.

Gangadharam is the ailing patriarch who runs an orphanage and is central to the family history. His health collapse and later acceptance of Pandu as his son mark a climactic shift in the inheritance dispute, making him pivotal to the resolution of the family mystery.

Saumitri is the local police inspector who collaborates with Pandu. She aids in the pursuit of the culprit and helps secure the arrest, providing official support to the detective's unofficial investigation and bridging the gap between law enforcement and private detection.

The film has a consistently light comedic tone due to the genre and the protagonist's clumsy, overconfident nature, which frames even serious situations like murder accusations with a sense of absurdity rather than dread. The ending is unambiguously happy with the villain's arrest, family acceptance, and a planned marriage.
