Beatrice gets tested to see which faction she belongs in. Her results were inconclusive, she's Divergent. Divergence is a threat to the city. To the Erudite. To the ones with power.
Beatrice Prior, or just Tris, chooses Dauntless (the faction that believes cowardice is the cause of most problems) over her old faction, Abnegation (the faction that believes selfishness is to be blamed for problems). Tris must be trained to become Dauntless by trainer Four, or Tobias. Tris falls in love with Tobias.
Erudite (the faction that believes ignorance is to blame for problems) wants to overthrow Abnegation to gain control of the government. Tris must try to stop the Erudite before it is too late.
