On the 74th yahrzeit of the Aish Kodesh, Rav Kalonymus Kalman Shapira of Piaseczno, may Hashem avenge his blood, Rav Shlomo Katz gathers in Efrat to remember the Rebbe of the Warsaw Ghetto — the tzaddik who taught us how to feel, how to pray, and how to stay alive inside.

Through niggun, story, and Torah, Rav Shlomo traces the journey of the Piaseczner Rebbe from his yeshiva in Poland to the hidden manuscripts buried in milk cans beneath the Warsaw Ghetto. We explore his teachings of emunah written in the darkest hours of Jewish history, his longing for Eretz Yisrael, his love for children, and his unbreakable belief that even in the pit of Gehenom, the soul can still sing.
