Manali's frostbit dawn clawed Arjun's bones as he ditched the bus, backpack heavy with Papa's revolver and Priya's sketchbook—her "Hero Bhaiya" doodle a flickering flame against blizzard howls. Rohan's parting whisper burned: "Vikram's cave fortress, Rohtang Pass. Come alone." Trust? A gamble after train "slip" and half-confession. Priya safe in Mumbai, her texts pure light: "Bhaiya, Himachal thand mat kha jaaye!" Laughter stung; family ties pulled him from abyss, but Rohan's blood—Vikram's son—threatened to snap them. "Papa, sach dikhao," Arjun breathed, boots crunching ice toward peaks that pierced indifferent skies.
Rohtang Pass loomed killer—winds screaming like Priya's kidnap wails, snow blinding vision. Flashback ambushed mid-trek: Boyhood Shimla trip, Rohan and he building snowmen, Papa's snowball wars, laughter echoing. "Dosti kabhi nahi tootegi!" Rohan vowed then. Lies now, yet train tears felt real—conflicted son warring father's shadow? Arjun's lungs burned oxygen-thin; altitude mirrored soul's thin ice. Cave mouth yawned ahead, guarded by frozen goons—Vikram tattoos iced blue. Heart thundered: Endgame.
Stealth slip: Arjun scaled cliff shadows, revolver silenced by mittens. First guard down—chokehold swift, pity flashing at man's "Ghar jaana tha" gasp. Inside, tunnels twisted labyrinth-cold, dripping menace. Whispers echoed: "Rohan bhai laaya cop ko... trap set." Rage ignited; Arjun's roar swallowed by stone: "Rohan, phir se?!" Priya's face fueled fury—he crept deeper, torch revealing arms caches, Parliament blueprints glowing sinister. Vikram's plan: National blackout, syndicate takeover.
Cavern heart pulsed evil: Vikram enthroned in furs, oily laugh booming. "Dhurandhar! Rohan ka tohfa." Rohan knelt beside—traitor pose? Arjun burst in, gun raised: "Priya ko chhoda, ab desh bachayega!" Goons lunged; snowy brawl erupted—fists crunching ice, blood steaming hot. Arjun dodged axe swing, countering knee to gut: "Papa ke liye!" Vikram watched amused, Rohan rising slow—ally or assassin? "Bhai, wait!" Rohan blocked a goon, fighting beside—old rhythm alive.
Showdown peaked brutal: Arjun vs. Vikram's elite, cavern shaking avalanches. One brute pinned him; ice shard to throat—Rohan intervened, snapping neck: "Arjun mera bhai!" Doubt thawed flicker; they synced savage, backs guarded. Vikram sneered: "Beta, utha gun. Papa ka raj!" Rohan hesitated, eyes tormented—love's war. Arjun seized moment, tackling Vikram: "Tune Papa mara! Rohan ko banaya puppet!" Fists flew; Vikram's ring gashed cheek, rage spilling: "Tera baap ne mera business chhina!"
Rohan shattered silence—gun on Vikram: "Bas, Papa. Arjun sahi tha... bachpan se guilt khaaya." Full reveal flooded: "Vikram ne tera Papa maara revenge mein. Mujhe teri family mein ghusaaya spy banaane. Par Priya... teri himmat... badal diya." Tears froze cheeks; Arjun's gun wavered—brother or beast? "Train slip? Bandra goons?" Rohan sobbed: "Tujhe test kiya... Vikram se alag hone ka. Maaf kar, bhai." Heart imploded—years' lies crumbling like snow walls.
Vikram lunged opportunistic—knife flashing. Arjun shoved Rohan clear; blade grazed ribs, fire exploding. "Nahi!" Rohan fired—Vikram crumpled, gasping shock: "Beta...?" Betrayal's mirror—Vikram's empire dust. Cavern trembled; avalanche roared. Arjun dragged Rohan out, Priya's sketch shielding faces from white death. "Saath bhaag!" Collapse sealed Vikram inside—icy tomb.
Outside, blizzard broke—stars witnessing. Rohan collapsed knees, sobbing raw: "Priya ko bachaya main... tere liye. Ab jail?" Arjun gripped shoulder, tears mingling melt: "Family pehle. Papa maaf karega shayad." Bro-hug crushed centuries' pain—forged new in snow. Priya called: "Bhaiya, news mein snow blast! Zinda?" "Haan, beti. Rohan uncle saath." Her joy healed cracks.
Manali lights twinkled below; helicopter whirred rescue. Vikram down, heist blueprints ash. But Rohan's path? Justice or jail? Arjun vowed silently: "Dosti tooti, par sil di." Himalayan cold forged unbreakable—Dhurandhar's heart, scarred eternal. Peaks whispered promise: Final battles dawn.
