A master of the Brazilian martial art, capoeira, Stevens pledges to straighten out a dozen of the school’s worst students by teaching them this demanding and highly-disciplined fighting style. Slowly, his program begins to work, giving the students new hope and purpose. But the local drug lord, himself a martial arts expert, vows to stop Stevens’ positive influence. Now Stevens must fight to save his own life, as well as the lives of his rebellious young students.
