In a world torn apart by an invasion of dimensional creatures known as Mrityudoots, humanity fights for survival against an overwhelming force. The creatures, emerging from mysterious rifts in reality, threaten to engulf the world, causing chaos and destruction. Amid this turmoil, a young man named Rahul, once seen as the hope of his family, struggles with his own insecurities and self-worth.

Despite being the eldest son, Rahul feels overshadowed by his younger brother, Rohan, a naturally gifted and strong individual who excels both academically and physically. While Rohan is the pride of the family, Rahul is labeled as weak, confused, and a failure. But when the world is plunged into a war against these otherworldly creatures, Rahul’s life takes an unexpected turn.

The government conducts a secret experiment to grant humans superpowers through exposure to the radiation emitted by the dimensional gates. Unlike his peers, who gain immense abilities, Rahul’s powers fail to manifest, and he loses his emotions, becoming a hollow shell of his former self. The government decides to use him as a secret Sentinel, tasked with hunting down traitors who secretly side with the Mrityudoots, known as The Immortal Assembly. However, as the war against the creatures rages on, Rahul longs to prove his worth and asks to join the fight.

Instead of receiving more power, the government develops a high-tech robotic suit for him, crafted from the bones of the fallen creatures. This suit, stronger than any metal, becomes Rahul’s weapon in the war. Equipped with the latest AI, Rahul becomes a formidable force on the battlefield, fighting to protect humanity from the creatures that threaten to wipe them out.
