Mercy is a film produced in 1973. This film reminds us of the only proud national station at that time, TVRI, which also aired this film. Santi (Dewi Irawan) and her friends from an orphanage foundation were having an outing at the beach. When Santi and Tina, her friend from the foundation were playing plastic ball, Santi accidentally threw the ball into the drinking glasses of a married couple named Mrs. Hartono (Tatiek Tito). Santi apologized, but Mrs. Hartono was not angry about it. The couple, Mr. Hartono (Bambang Supeno) and Mrs. Hartono, were a couple who had longed for a child, but had not been given one. Until the two of them decided to adopt a child from an orphanage foundation. And the choice fell on Santi, who had indeed stolen the hearts of the couple. In Santi's farewell, the song Bintang Kejora was presented, sung by Santi's friends from the orphanage. Among Santi's friends, Tina was the closest friend who was always the place where she poured her heart out. Before being taken by the Hartono family, Santi was given a doll made by Tina. They both finally said goodbye, and Santi was taken by the Hartono family. ***** The days living in the Hartono family's house were so beautiful for Santi, Mr. and Mrs. Hartono loved Santi very much. Santi's presence made the Hartono family's life happier, holidays and outings and whatever Santi needed were always fulfilled. The blessing of Santi's presence in the Hartono family's house increased after Mrs. Hartono finally became pregnant with their child. Mr. and Mrs. Hartono loved Santi even more. Until one day Mr. Hartono had to be assigned to study in Japan, Mr. Hartono's older sister who was usually called Mrs. Dhe (Chitra Dewi) came and was assigned to look after his pregnant wife until Mr. Hartono's study assignment was completed. Mrs. Dhe was an old spinster who had not married until she was getting old. Mrs. Dhe's presence brought disaster to Santi since the first meeting, she was already unfriendly to Santi. Santi was often shouted at and treated like a servant by Mrs. Dhe. Santi felt uncomfortable and often complained to the maid named Harjo (Harjo Muljo). Meanwhile, Mrs. Hartono herself could not do anything seeing her sister-in-law's behavior towards Santi. Auntie's job was just to get angry and nag. Work that was not supposed to be done by Santi, had to be done by Santi. Santi was considered a child of unclear origin, living under a bridge and other words that were very hurtful to Santi. One day when she was boiling water, Auntie told Santi to turn it off. However, Santi accidentally spilled the water that had just boiled, and finally hit Mrs. Hartono until she fell. Auntie was very angry with Santi because she considered Santi an adopted child who could not be used and hit her. Santi was sad, finally in the middle of the pouring rain, wearing the uniform she used to wear from the orphanage foundation, Santi ran away from Mrs. Hartono's house to her orphanage. Meanwhile, at the hospital, Mrs. Hartono kept calling Santi's name, until Auntie panicked and told Harjo to pick up Santi at home. However, Santi was not found, so Harjo finally looked for Santi on street corners, but she was not found. Finally, through Harjo's instructions, it was discovered that Santi had said she would return to the foundation. Pak Hartono finally rushed home and immediately met his wife at the hospital who always asked about Santi. However, Pak Hartono always covered up Santi's whereabouts. Finally, Santi was picked up from the orphanage by Pak Hartono and Auntie. Auntie apologized to Santi, and finally Santi agreed to be taken back by the Hartono family.
