A fragrant way to pass away (1974)

Due to complaints, an inspector comes to a small construction industry cooperative in Bihar. The three leaders that committed embezzlement and abuse begin to think about how they could escape from being held accountable. The president knocks down and robs the inspector, but they don't find the compromising documents on him. Therefore, they decide that one of them must sacrifice himself with a poisonous liquid called "fragrant road to nowhere"...
