After losing a memory from an accident, “Tan” (Mario Maurer) tried to find his identity because he could not remember anything except his name. He doubted himself who he was and where his family is. Eventually, he found something that led him back to his home sweet home.

There, he met “Tubtim” (Wannarot Sonthichai) his twin sister who is living with “Chiwin” (Peter Noppachai) a widower and his two children, and “Waw” (Nabhada Sukhakrit) a house keeper who raised him up. The more he knows them, the more he learns to fear of their secrets. No matter how hard he tries to go out of the house, he is getting closer to it.
