Lost in Time (2016)

On the twentieth anniversary of his wife's death, Rodger returns home after a hard day's work to find two peculiar things waiting on him, a strange man sitting on his couch and a strange door in his hallway. Neither of these two things belong. The strange man explains that Rodger can walk through this door to another time, and he can come and go as he pleases. When he walks through the doorway, he walks into the past to the western era where he finds a doppelgänger of his deceased wife. She looks like her, sounds like her, even laughs like her, but is it her?
