DISCLIAMER- Strictly adviced Don't show this movie to children under 11 years it is very disturbing for adults.
This movie is very good, a great patriotic movie of a forgotten freedom fighter it depicts the cruelty of Britishers on Jallianwala Bagh protest that they crushed down by killing so much Indian without any guilt all people were innocent and they were attending protest without violence but British Government was afraid that they crushed all protesters of India like Shaheed Bhagat Singh, Sukhdev, Rajguru, Subash Chandra Bose and many other about whom we don't know much and Sardar Udham Singh is one of them. He and HSRA started the main thing needed that's anger in people. Killing Bhagat Singh so cruelly made people angry that lead to freedom of India. This Movie depicts how Sardar Udham made a small part in independence but a important role. He killed Michael O dwyer . Michael was only person permitted the massacre of Jalli. Bagh. Due him many people lost their family members. The blood bath make you disturb for many many days and common man who experienced this can become mad after seeing so much dead people lying bloody.
I suggest you to watch movie but keep calm.
