Ex-mountain rescue ranger Gabriel 'Gabe' Walker (
Sylvester Stallone) is reluctantly called out of self-induced retirement to rescue a group of hikers stranded in the Colorado Rocky Mountains. Accompanied by former coworkers -- rangers Hal Tucker (
Michael Rooker) and Jessie Deighan (
Janine Turner) -- they go in rescue, not knowing that the 'hikers' are actually thieves who have just robbed a U.S. Treasury plane of $100,000,000 in uncirculated bills prior to crashing their plane, and what the thieves, led by former military intelligence agent Eric Qualen (
John Lithgow), want is the rangers' help getting the money back.
