Sometimes

Krishnamurthy (Prakash Raj), Deepa (Sriya Reddy), and Bala Murugan (Ashok Selvan) are three of seven strangers who give blood for an AIDS screening and cannot stand the wait for the result. They bribe the technician to learn the answer early, and it comes back that exactly one of them is positive. Priyadarshan keeps the group in close quarters, where each person watches the others and quietly hopes it is not them.
