On a professional trip, Meera Mohan finds herself stuck in the quaint little village of Kanakapuram amidst unprecedented floods in the state of Kerala. She is fascinated by the story of a haunted house, its serpent grove, and cherishes her new friendships. Bhuvanamma, a gentle old widow who is also an excellent cook, Hussain, the caretaker at the company guest house, Unni and Rani, a young couple torn between their respective ambitions, Leena, an ethnobotanist and Hari, an architect—form the motley gang at Kanakapuram. She rekindles her love for her native culture through them, until… …mysterious deaths occur at the house, and Meera gets unwittingly involved. Before she can extricate herself from the investigations, her friend and colleague, Cara, is found dead in the United States. Who can Meera trust? Is the house really haunted? Who are the serpents?
