Heaven movie plot

Philippa, a 29-year-old English teacher, decides to get revenge on his family, targeting a drug criminal who looks like a legitimate businessman but is actually full of evil. She quietly hid the bomb in her backpack and infiltrated the drug criminal's office building. After she made sure everything was in place, she put the bomb backpack in the wastebasket outside the door he had to go through. When she brought out his secretary, she also left quickly, and everything went as planned. But somewhere, an accident happened. The cleaning lady put the backpack of the wastepaper basket into the cleaning car, and then entered the elevator. Standing inside was a father and his two children. There was a loud explosion and four people were killed on the spot. Philippa, who fled the building, thought her revenge had been avenged. That night, the police broke into her apartment and arrested her. She had no denial of the case and no remorse for what she had done. In the police station, Philippa was severely interrogated, and one of the policemen, Philip, 21, was responsible for recording everything. Philippa asked for the interview to be conducted in English, and Philip was responsible for the translation. At this time, Philippa finally knew the truth of the case. She killed four innocent people, and her revenge target is still alive. After Philippa knew everything, she was depressed and fell into a coma. When she woke up, only Philip was by her side. She held his hands, and the two looked at each other for the first time. Philip leaves the room and passes outside the director's room, where he overhears the director interrogating the drug criminal that Philipba intends to kill. Philip returned home and told his 11-year-old brother, Evel, who was a student in Philippa's English class. That night, Philip slept badly and confessed to his father that he was falling in love. The interrogation continues, Philippa will tell the whole story, and frankly does not believe the police. She suspects that the top police officers and drug offenders colluded. Philip beckons Philippa back to the prison cell, and secretly gives her a miniature dictation device, and secretly communicates with her. The secret of the two was known by the director, and they searched Philippa's cell and found Philip's plan to help Philippa escape. But this is just Philip's trick to avoid everyone's eyes and ears, and he is subtly setting up a more shrewd layout, making the most daring attempt for Philippa's freedom   .
