十年前，平海站派出所民警赵鹏程在执勤时遭遇持枪嫌疑人，开枪时“哑火”，关键时刻师傅徐雷挡在他面前击毙罪犯也中弹致残，这使赵鹏程在家庭和工作上背负上沉重的精神压力。十年后，平海所值班室发生了“走火”事故。当事民警刘长路顾及他人前途决定隐瞒不报，然目击“走火”的赵鹏程却深陷情与理的抉择中。“走火”事件被人举报，引发平海所的人际纠葛。办案时，赵鹏程和刘长路遭遇袭警，刘长路开枪警告时，一颗子弹误伤路人，造成意外“失火”，由此被告上法庭。案件引发警察用枪法律层面上的思考，律师迟玉和赵鹏程找到关键证据，洗清刘长路罪名，赵鹏程向刘长路坦承是他举报了“走火”，却遭到大家误解。当再次面对枪口，赵鹏程挡在刘长路面前秒杀罪犯，赵鹏程的“开火”打碎了当年“哑火”的精神枷锁，让大家理解了他举报“走火”的正确意义 。
Tong, no unit or individual is allowed to occupy the fire exits to build houses, pile things and set up stalls. The existing flammable building intensive areas in cities and towns should be gradually transformed in combination with the overall planning of cities and towns, and contiguous transformation can be carried out if conditions permit.

Requirements for setting up fire lanes in factories, warehouses, storage yards, storage tank areas and large public buildings According to the reflection of each fire fighting squadron in fire fighting practice, When a fire occurs in a large area of factories, warehouses, storage yards and storage tank areas, the fire burns very fast, the fire is fierce, and the fire fighting lasts for a long time. If there is no fire ring lane and flat open space, it will inevitably cause fire vehicles to be unable to enter or leave, which will inevitably cause blockage and make it difficult for fire engines to approach the fire site. Therefore, fire lanes should be set up in factories and warehouses. When a Class a, Class B and Class C factory building occupies an area of more than 3000 square meters or a Class B and Class C warehouse occupies an area of more than 1500 square meters, a flat open space with a width of not less than 6m for fire engines to pass through can be set up along its two long sides. Open yard area for flammable and combustible materials, Liquefied gas storage tank area, For Class a, Class B and Class C liquid storage tank areas, there shall be large public buildings such as fire lanes or flat gymnasiums with a width of not less than 6m and a space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters that can be passed through by fire engines. Because of the large volume, large floor area and large and dense personnel, in order to cause fire, there shall be large public buildings such as the gymnasiums with a flat space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters.
