In 1966, The Wonder Boys, one of America's top rock bands, embarked on a flight from Anchorage to Fairbanks for a concert. However, their plane mysteriously vanished en route. Adding to the mystery, the band's manager, who opted out of the flight, disappeared the following day, leaving no trace.
Fast forward nearly six decades to the present day. Bush pilot Scott Harper, accompanied by his recently adopted daughter Michaela and his former police dog Max, stumbles upon the wreckage of the missing aircraft. In it are the skeletal remains of its two pilots and seven passengers. But official records only account for six passengers. Who was the seventh?
