title: The Mountain Between Us (film)
text: In January , after the cancellation of their flight out of Boise Airport to Denver , due to stormy weather , neurosurgeon Dr. Ben Bass ( Idris Elba ) and photojournalist Alex Martin ( Kate Winslet ) hire Walter ( Beau Bridges ) , a local private pilot to get them to Salt Lake City , for connecting flights to Alex 's wedding in New York ( scheduled the following day ) and Ben 's emergency surgery appointment in Baltimore , Maryland . As they board a small plane , along with Walter 's dog , Alex asks Walter if he has filed a flight plan , to which he says no , he does n't need to , as `` ... it 's still light out ... '' , they 're flying VFR , and they 'll beat the approaching storm . He tells them he flew combat missions in Vietnam , so unless somebody is shooting at them , they 'll get there . Minutes after takeoff , Walter points out they 're over the High Uintas Wilderness , ' a million acres of pure ass wilderness ' . Alex notices the storm is ahead , as Walter suffers a stroke , causing the plane to crash on a mountaintop . Ben , Alex , and the dog survive , with various injuries , but Walter is killed .
