Truman lives as the main character in an immensely popular TV show. He lives in the fake world of Seahaven, along with him are many paid actors put in to simulate a coherent and realistic reality. His father had died in a boating incident which has created a phobia of the sea and preventing him from leaving. He has a wife named Meryl and a best friend named Marlon.
Several odd events make Truman suspicious of his surroundings. A stage light fell from the sky and he sees a homeless man in which he is positive that he was his father. As well as, while he was in college he met the love of his life named Sylvia. She admitted to him that his life was fake, but he failed to make sense of it and Sylvia "moved to Fiji."
Truman realizes the flaws of his created reality. His car stereo changes frequencies to a man describing his every move. He enters a building to notice the elevator didn't have a back wall but instead a changing room. He shows his wife that things are running on a loop and he attempts to leave Seahaven when he is stopped by some sort of predicament.
Truman fully realizes his reality is fake. He escapes his home and sets sail while the people running the simulation are confused. They begin a search party to find the beloved star of the show. Christof is the sociopathic director of the show. He notices Truman is at sea and bombards him with a storm.
Christof finally loosens the reigns and stops the storm. Truman continues to venture out into the unknown until his boat hit the end of the TV set.
Along the inside wall of the set Truman notices stairs leading up to the exit. Before exiting the voice of Christof booms throughout the space. He tries to convince Truman that life outside isn't so glamorous. Truman is not persuaded by his speech and exits the set into the real world....
In case I don't see ya: Good afternoon, good evening, and good night!
