Jeff Wigand is a man who used to work for a big tobacco company in America. His job was to help make cigarettes taste good so people would want to buy them. But Jeff didn't like it because he knew that smoking cigarettes was really bad for people's health and could make them very sick.
One day, Jeff found out that the tobacco company he worked for was doing something very bad. They knew that smoking cigarettes could make people sick, but they didn't want anyone to know because it would hurt their business. So, they were hiding the truth from people and even lying about it. This made Jeff very upset and he knew he had to do something to stop it.
Jeff decided to tell the truth about what the tobacco company was doing, even though it was scary and he could get in trouble. He talked to a journalist and shared all the bad things he knew about the tobacco company. This helped people find out the truth about smoking and the bad things tobacco companies were doing.
Jeff became very famous for being brave and telling the truth. He helped people understand that smoking is very bad for us and that we shouldn't believe everything that big companies tell us.
