After an anonymous phone call about a spacecraft that would have crashed in a frozen wood, two police officers find evidences that the event really happened and apparently one Martian had walked away from the spot. They drive to the nearby Hi-Way Café and they find a bus stopped and seven passengers waiting the reopening of a snowed in bridge. However the driver tells that he had only six passengers when he parked the bus. While interrogating the travelers, weird things happen in the diner, with the lights switching on and off and the turntable turning on and off. When the passengers are released and the bus follows his travel, one passenger returns to the diner and discloses a plot of invasion of Earth.
"Will the Real Martian Please Stand Up?" is one of the best episodes of this great series. The intriguing story has ironic and witty dialogs, funny characters and situations and a surprising and totally unexpected plot point in the very end. My vote is eight.
Title (Brazil): "O Marciano" ("The Martian")
