A story of a family as victim of Lapindo’s mud, Sidoarjo. The whole life of Delta Santoso (Ilman Lazulva,Vino G. Bastian) is dedicated to express his gratitude to his mother, Sriyani (Happy Salma)—in whatever circumstance and ordeals. Sriyani’s misfortune isn’t only Lapindo’s mud, but also being left by her husband who elopes with another woman without clarifying their marital status. As the result, Sriyani has to work hard to make a living so that her children, Delta and Iqbal (Reza Farhan Bariqi, Rizky Hanggono) can go to school. She becomes a laundry worker and sells lontong kupang, a dish, from her old bicycle.
