It's about a man named Edward Bloom who tells the stories that happened in his life, like Forrest Gump. And his son who doesn't believe these so called fabricated tall tales. So Edward Bloom and his son have a three year falling out where they dont speak to eachother, until Edward Bloom stops the Kemo therapy for his cancer
So Edward's son rushes home to ALABAMA just like Forrest Gump, to reconcile with his father too see if he can get the truth from any of his actuall life.
Rog was right, this movie did have aspects of Forrest Gump. Go see it anyway.
