In ‘Oxygen’ none of the characters are ever what they seem. The calm and composed Krishna Prasad has a dukh bhari daastan in flashback that no one expects; the much-respected family has a dark secret that they have kept from everyone, including their daughter. The daughter, who seems to be a simple village belle, somehow turns into a computer expert by the end of the film, but we digress.

Gopichand’s introduction scene is not the only similarity between ‘Oxygen’ and ‘Adirindhi’. While ‘Adirindhi’ was an entertaining masala offering that focused on the corruption that lies rampant in the medical field, ‘Oxygen’ focuses on the illegal tobacco industry that is rampant in the country. While Vijay’s character turns vigilante to root out the corruption there, Gopichand’s character here does the same, if only to find the sole person responsible for it all.
