It might be fairly accurate. It could have captured the essence of the real story well.
To determine how accurately 'Jhund' portrays the true story, we need to look at several factors. First, the characters. If they are based on real people, do they behave and react in ways that are consistent with what really happened? Second, the setting. Does the movie recreate the real - life environment convincingly? Third, the sequence of events. Are the major events in the movie in line with the true story? While it's hard to say for sure without in - depth research, it's possible that the movie has taken some creative liberties while still maintaining the core of the true story.
The movie might be accurate in some aspects. For example, it may have depicted the main events correctly. But it could also have made some changes for the sake of entertainment. Maybe it added some fictional elements to make the story more engaging while still staying true to the overall spirit of the true story.
