Plotsky was the son of Rabbi Chaim Yitzchak Ber Plotzker of Kutno, who was first a follower of Rav Chanoch Henich of Alexander, but who then became a follower of the Sfas Emes of Ger.
Thousands of followers of rebbes such as the Gerrer Rebbe Yehudah Aryeh Leib Alter (known as the Sfas Emes), the Chernobyler Rebbe, and the Vizhnitzer Rebbe flocked to their towns for the Jewish holidays and followed their rebbes' minhagim (Jewish practices) in their own homes.
