As a new tyrannical ape leader builds his empire, one young ape undertakes a harrowing journey that will cause him to question all he's known about the past and to make choices that will define a future for apes and humans alike.

A group of scientists in San Francisco struggle to stay alive in the aftermath of a plague that is wiping out humanity, while Caesar tries to maintain dominance over his community of intelligent apes.

When the plane owned by the "Yukon and Columbia Mail Service" crashes, RCMP Sergeant Renfrew (James Newill) and Constable Kelly (Dave O'Brien) suspect murder. Their suspicions are confirmed when Renfrew finds the control stick has been jammed, forcing the plane to fly in one direction until the gas ran out. Mine owner Louise Howard (Louise Stanley) reports that her superintendent is missing. The Mounties find him murdered and that too has been made to look like an accident. A new mail service pilot, Bill Shipley (Warren Hull), arrives. He had gone to training school with Renfrew but had been cashiered for misconduct. The Mounties discover that Raymond (Karl Hackett), who had been working for Louise, really owns the flying line managed by Yuke Cardoe (William Pawley.) They find proof that all the gold from the mine isn't being turned over to Louise, and suspect that Raymond and Yuke are stealing the gold and shipping it to Seattle by plane.

On January 26, 1950, a US Airforce troop plane left Anchorage for Montana with 44 people on board. The crew of the Douglas C-54 Skymaster #2469 was supposed to check in every half hour along the route. As the aircraft crossed into Yukon, they radioed the tiny outpost of Snag to say that there was ice forming on the wings, but otherwise all was well. After that, the Skymaster disappeared. And to this day no sign of the aircraft or its passengers has ever been found. This fascinating Yukon-shot documentary tells the stories of the victim’s families and an intrepid group of Yukoners striving to give those families closure by searching every summer in hopes that the Skymaster will finally turn up.
