Josh Wheaton, a Christian in college, enrolls for a class of philosophy taught by an atheist Professor, Jeffrey Radisson. The Professor begins his class by listing famous philosophers to show their similarity in belief that God does not exist. In this class, for a student to get the required pass grade, he has to declare through signature that God is dead. This rule is stated by the atheist professor. All the students apart from one, Josh Wheaton, sing the declaration. At this point, josh is at crossroads and has two options to chose from: he should either deny his faith, or chose to fail in this class. It is important that Josh excels in this class if he is to get the entry points to law school. The professor does not just let Josh go. Instead he welcomes him to debate the topic in the presence of the class members who should decide who the winner of the debate is. His arguments should be well researched and he should present them in an intellectual manner.
The students go through the first three lectures where the professor invites Josh to convince the class and him that God exists. For the first two debates, Josh does not seem to get any progress as Jeffery counters all his arguments with sensible points of argument. At this point, most of the students including Josh’ girlfriend Kara try to convince him to either follow Jeffrey’s rules or drop out of the class, after all he does not seem to win the argument.
