Bulgaria is under Ottoman domination. Levski, the Bulgarian national hero, arrives in a small town. He gathers the members of the revolutionary committee set up by him but the Turkish authorities get wind of the meeting and the conspirators disperse. A schoolteacher Hristina is in love with Levski. The Turkish spies watch her and the priest Nikola, who sympathizes with the cause. The police arrest them and torture. They torture also Levski's mother - throw her in the well. Changing disguised, Levski closely follows the very posse sent to track him down. After surmounting all sorts of obstacles, he manages to free Hristina. The blinded priest continues to pray for his enslaved brethren. A miracle occurs: church bells start ringing of their own accord. The miracle strengthens the people that liberation is coming soon.
