Not sure if it sounds plausible
So in comparison mode it has elements of National Treasure, Oceans's Eleven, Assassins Creed, The Witcher, and Now You See Me,
The main story is about this person, Not a teen, that gets initiated to be someone who has better than human listening and perception when it comes to detecting lies and falsehoods. The previous Scholar died in this process as they were being chased by an unknown enemy. The person escapes while confused about what they see and hear, but understanding that this will somehow help them make change in the world.
After doing some research online, they understand some myths and prophecies about what has happened and given their own personal history, they know what to do next as a test. The test goes well and some information comes to light about major political events that will shake much of The Scholar's community and nation. He devises a plan to infiltrate and discuss the matters with the top most official.
In some way they recruit a couple of helpers, reach an event or party to locate the subject through short spy-like conversations where The Scholar knows exactly what to say to flatter and disarm the target, sneaking verbally into a closed room with the big bad guy who is responsible for the changes. They find the alterior distrustworthy motive, something happens, and the big bad quickly puts together who they might be, sends security so they have to escape.
After the big bad 1 sees what happens, they recruit big bad 2 who is much more secretive and distrusting, so there are a few scenes with people who can pinpoint the big bad 2. The Scholar and associates find and draw out big bad 2's information. The information gets sent to the public media and the officials get their deserved justice.
In closing, The Scholar understand a deeper meaning of responsibility and ends up inclusively passing their gift to an associate toward the end as they proved beyond a shadow of a doubt their dedication to the truth in the face of danger. The story ends with those two splitting to different parts of the world to seek out new corruption.
