Nidhi and Vikram have started a guest house in the beautiful city of Shimla. They get 2 guests - Sam and Mrs. Roy. Soon, an unexpected guest Mr. Rehman shows up when his car breaks down nearby. While uncomfortable, they still accommodate Mr. Rehman since there is also a snow-storm in progress and most roads are blocked. Soon, things turn sinister when Nidhi and Vikram learn that a murder has taken place near the guest-house. Soon, a cop investigating the murder shows up at their doorstep suspecting that the murderer must be hiding in their guest house, given the snow-storm.
