Tris is getting ready for her Aptitude test with her mom. She is very nervous about the Faction she will get from the test.
Tris Finds out from her Aptitude test that she is Divergent. Tris is frightened by this because if you are Divergent you will get killed by everyone else so she'll have to keep this a secret from everyone... even her parents.
It is time for Tris to pick her Faction/ Job that she will stay in for the rest of her life. In order to pick one of the 5 Factions/ Jobs Tris must cut her wrist and drop her blood into the container of her choice. Each Faction has a bowl labeled for them. After thinking Tris picks Daughtness which are the cops and risk takers of the city.
Tris arrives at Daughtness headquarters with other new people. The head of Daughtness is Eric. Eric decided that they will now have tryouts to get into Daughtness which never happened before. The people who do not make it become factionless which is basically homeless.
Tris makes it into Daughtness and then she gets welcomed by putting a chip in her neck. The chip also hypnotizes her to kill and destroy one other rival faction called Abnegation.
A war brakes out and then gets settle by Tris. She does this by braking the system which shows that she is Divergent. She now must run away for her survival so she does not get killed.
