Hiralal is a soldier of BSF. He was keeping an eye on the border with his senior officer. They noticed a healthy cow and officer ordered Hiralal to catch the cow.
When he was trying to catch the cow, the cow kicked him and escaped. Right after that he discovers a tunnel and reports to the officer. The officer orders him to get into the tunnel in order to find terrorists or the cow. Hiralal refuses but after being threatened by the officer he agreed.
On the other side, the notorious cow reached the No Man’s lands through the tunnel from Indian border. Jamal who is a soldier of BGB catches his gaze upon the healthy cow and tries to catch it but the cow kicks him away too.
Hiralal reaches Bangladesh border and gets confused about the location. At that time he meets Jamal. They both get very scared and hides under shield. Jamal starts a conversation to find out what is happening. When Hiralal takes part in the conversation, lots of political history, murders, tortures comes up. They talk about the sufferings, killings and injustice of both sides which includes the murders on border, rape, religious collision and what not in both sides. This heats up the conversation which boils their young blood and their fight takes a turn to firing each other.
This fight digs more to the history and brings out that Hiralal is from Barisal and he was thrown out of the country after robbing their property because he was Hindu. After everything they both realize, no matter what the religion is, which country are they from, the division of barbed wire, tunnels cannot deny the fact that we are all same, we are brothers.
When they step forward to embrace each other, they were shot from behind and dies on each other. Even the cow comes back to mourn for the cruel murder.
