He prefers to partake in the latter as he certainly does not see himself as an enlightened being. Aaron has come to break some bad news to his estranged father. A minor event in the lab leaves Aaron's father so upset that he has fatal heart attack. Aaron is unknowingly set out on a journey to redefine the relationship with his father and the world he now lives in, thanks to a homeless man who serves as his mentor and guide.
