"How do you know? Can you say you know?"

Two twin women, a man, a dog, and a letter. Leading their own lives, but sometimes accompanying each other or running away from each other. Some lose their legs, some die. They guessed about each other in the process in which time, space, seasons, lies and facts were mixed up. But, all of their guesses are wrong. Not knowing their whereabouts and themselves with full of unknown ambiguity. But, they move on and on.
