How is Truman manipulated in the show?

Please provide more context! Which show are you referring to?

For example, are you talking about:

* "The Truman Show" (1998), where Truman Burbank is the unknowing star of a reality show?

* "House of Cards" (2013-2018), where Frank Underwood manipulates President Garrett Walker?

* "The Crown" (2016-present), where Queen Elizabeth II is portrayed as being influenced by various advisors?

Once you specify the show, I can provide a detailed analysis of how Truman is manipulated.
