Lea is drawn to smart, confident new student Tristan and his rebellious defense of misfits, but is unaware of his double life.

Tristan defends his friends when the school's neo-Nazi contingent attacks them during a weekend hangout; Lea breaks away from her former circle.

After their protests go viral on social media, Lea pressures Tristan to allow more members into the Wave.

After a poorly planned raid on a slaughterhouse, the Wave spins out of control and a rift develops between Lea and Tristan that tears the group apart.

The original five members of the Wave reunite and take action against a right-wing politician and an SUV dealership.

After blood is shed for the movement, the Wave's remaining members plan a new action that crosses the line between peaceful protest and violence.
