Mirzya is a tale of lovebirds who were never meant to be together. Mohnish (Harshvardhan Kapoor) is a horse groomsman who reconnects with his childhood friend Suchitra (Saiyami Kher), a soon to be princess. Both reconnect after a childhood incident where Mohnish shoots the schoolmaster and is sent to a juvenile correction facility, while Suchi is sent to London for higher studies. Years later, Suchi returns to India and gets engaged to Prince Karan. She learns riding from stable-hand Aadil, who turns out to be her childhood friend, Mohnish. They reconcile and Aadil confesses to her father about his childhood murder and wishes to marry Suchi. Her unforgiving father and Karan hatch a plot to get rid of him. Despite their attempts to kill him, Aadil survives. Suchi agrees to marry Karan, and on their wedding day, they elope, but are chased down by police, Suchi’s father, and Prince Karan. Suchi swallows poison and Aadil is shot as they die in each other’s arms
