Tom Slick: Mystery Hunter chronicles the larger than life adventures of Tom Slick (Owen Wilson) and his steadfast pursuit of the unknown, culminating to one of his greatest and most mystifying expeditions: his 1958 hunt for the Yeti. Tom Slick’s epic story is told through hidden tapes found by his granddaughter Liv Slick (Schuyler Fisk) in the attic of her mother, Claire Slick (Sissy Spacek). What is a climactic tale of a legendary man and his hunt for the Yeti is, for Liv, the discovery of a grandfather whose life was largely shrouded in mystery… until now.
