Ek din DCP Chitrole ke office mein kuch confidential documents ghayab ho jate hain. Yeh documents CID ke ek bade mission ke bare mein the, jo agar galat haathon mein chale gaye, toh desh ki suraksha khatre mein aa sakti thi. Investigation ke dauran, saboot is baat ki or ishara karte hain ki Daya aur Abhijeet hi is chori ke zimmedar hain.
DCP Chitrole ko yeh baat had se zyada chubhti hai, kyunki Daya aur Abhijeet ne hamesha vafadari se kaam kiya hai. Lekin saboot itne pakke hain ki unhe bhi shak hone lagta hai. Chitrole sir ek naye undercover officer, Sam ko bulaate hain, jo pehle se hi CID ke ek dangerous mission se laut raha tha. Sam ko kaha jata hai ki woh Daya aur Abhijeet pe nazar rakhe, unke har kadam ka hisaab rakhe, aur pata lagaye ki kya woh sach mein doshi hain.
Sam apni investigation shuru karta hai, aur dheere-dheere Daya aur Abhijeet ke aaspaas ka ghera sakht karne lagta hai. Daya aur Abhijeet ko yeh sab samajh mein aata hai lekin woh khamosh rehte hain, apni nirdoshita ko sabit karne ka ek mauka dhundhte hue. Lekin ek raat aisa kuch hota hai jo puri kahani ko palat kar rakh deta hai.
Daya aur Abhijeet ko pata chalta hai ki ek badi conspiracy ho rahi hai jismein unhe fasane ki koshish ki ja rahi hai. Yeh conspiracy kisi baharwale ki nahi, balki CID ke ek andar ke aadmi ki hai, jo ek international criminal gang ke liye kaam kar raha hai. Yeh shak unhe Sam par bhi hota hai, lekin Sam khud ek twist ke saath saamne aata hai aur batata hai ki usse bhi phasaya ja raha tha.
Daya, Abhijeet aur Sam milkar us mastermind tak pahunchne ki koshish karte hain, jo DCP Chitrole ko bhi maarne ka plan bana raha hota hai. Ek zabardast action sequence ke baad, finally mastermind ka pardafaash hota hai aur yeh sabit ho jata hai ki Daya aur Abhijeet nirdosh hain.
DCP Chitrole, Daya aur Abhijeet se maafi maangte hain aur Sam ko unke sath team mein permanently add karte hain.
