A pair of ex-Navy SEALS and a mysterious homeless mountain man - all with a shadowy shared past at Afghanistan- must join forces when terrorists take over the St. Louis Gateway Arch in the middle of a raging blizzard. More
SYNOPSIS: Afghanistan. DUNCAN and CARTER are the only survivors of an insurgent ambush on their Navy SEAL TEAM SIX. Lost and wounded amidst the snowy crags, they are saved by PUN, a mysterious mountain man who does not speak.
Pun leads them back to their base. Duncan lets the CIA take Pun away for “questioning.” Carter is furious, and their friendship ends.
St. Louis. Years later, Carter is a detective, and Duncan works for the Secret Service, protecting a Chinese dignitary who is visiting the Arch.
A team of Uyghur ultra-nationalists led by YUNUS seizes control of the Arch, taking the dignitary and his family hostage. With the help of a Japanese mercenary hacker, THE GEEK, they rig up a mysterious black box that suffuses the Arch in a strange blue electric glow.
A snowstorm descends, delaying any help that might arrive. Carter and Duncan reluctantly set aside their differences long enough to do what they can to stop the Uyghur.
But they are surprised to get some unexpected help from… Pun! After the CIA released him, Pun has been living on the St. Louis streets. He catches the scent of his old friends, and follows them into the Arch.
A SWAT team finally struggles through the storm, and tries to enter the Arch, only to be zapped by the electrical field. Pun is unaffected by the field, but the charge blows off his clothes, revealing something not quite human… Pun is a descendant of the yeti!
With time running out, the two ex-SEALS and Pun the yeti-man take on the ultra-nationalists. But none of them realize that they are all pawns in a larger game being played by a shadowy figure behind the scenes…
