M. Night Shyamalan's Will Smith movie has an actual plot synopsis you can read, if you can get past his character's name
Here is the newly released plot description for the previously announced After Earth, M. Night Shyamalan's post-apocalyptic sci-fi film about a ravaged planet whose only real inhabitants are Will and Jaden Smith, with the twist being that it is a present-day documentary. Actually, we don't know what the ending will be, because we stopped reading after "Legendary General Cypher Raige (played by Will Smith)." If you make it past "General Cypher Raige," let us know what happens. Or don't, that's okay too.
