Chill Factor

Here is a rephrased version of the section:

Dr. Richard Long's (David Paymer) life has been forever marred by the devastating consequences of his own covert military experiment on a remote Pacific island ten years prior. The catastrophic event claimed the lives of 18 American servicemen and his assistant, leaving Long to grapple with the haunting memories of that fateful day. Now residing in the small town of Jerome, Montana, he continues to conduct scientific experiments at the local US Army base, but finds solace in his tranquil fly-fishing excursions with Tim Mason (Skeet Ulrich), a former troublemaker who has since found redemption working at the local diner.

Long's tranquility is disrupted when Colonel Andrew Brynner (Peter Firth), a former military officer who took the fall for Long's experiment, arrives in town. Free from prison after serving ten years for a crime he didn't commit, Brynner seeks to exact revenge on the government by stealing and selling Long's highly volatile, blue crystal substance, dubbed "Elvis." To achieve his goal, Brynner assembles a team of former US Army soldiers-turned-terrorists, including the icy Vaughn (Hudson Leick), and sets out to exploit the substance's devastating potential.

Long, however, has already taken precautions. He had entrusted Tim with the substance, along with detailed instructions on how to keep it below 50 degrees Fahrenheit - a critical temperature that, if breached, would trigger a catastrophic explosion capable of destroying everything within several hundred miles.

When Brynner and his team clash with Mason and Arlo (Cuba Gooding Jr.), a charming ice cream delivery man, the unlikely duo finds themselves on a perilous journey to Fort Magruder, some 90 miles away. Despite their initial animosity towards each other - Arlo was forced into transporting the substance by gunpoint at Mason's hand - they bond over their shared quest to evade Brynner and his cohorts. With the guidance of Colonel Leo Vitelli (Daniel Hugh Kelly), a seasoned veteran with a wealth of experience, Arlo and Mason must navigate treacherous terrain, avoid the prying eyes of local Deputy Pappas (Jim Grimshaw), and keep "Elvis" from reaching its explosive potential.

As Arlo and Mason finally breach the perimeter of the heavily fortified facility, they're met with a deadly surprise courtesy of Brynner and his ruthless team. The sinister duo has no intention of leaving any witnesses to attest to their nefarious plan, which involves detonating the device in a long-abandoned weapons testing facility. With calculated precision, Brynner sets out to eliminate both Arlo and Mason, but their timely arrival on the scene by the military proves to be a game-changer. The device explodes, wiping out Brynner's team, while the rescuers successfully extract Arlo and Mason from harm's way.

In the aftermath of the chaos, Colonel Vitelli arrives on the scene, showering praise upon the duo for their daring exploits. However, it soon becomes apparent that Vitelli is more interested in maintaining a veil of secrecy than in acknowledging their bravery. As tensions rise, Arlo and Mason reveal their intention to expose the U.S. government's decade-long complicity in using unstable nuclear weapons, threatening to upend the status quo and spark global outrage.

Vitelli, determined to protect his employer's interests at all costs, offers a hefty sum of money to keep Arlo and Mason silent about their harrowing experience. However, he also warns them that should they decide to defy him and reveal the truth, they'll become targets for elimination by those who seek to maintain the secrecy surrounding the weapon's existence. With the stakes raised to catastrophic levels, all three parties – Vitelli, Arlo, and Mason – depart the area in a helicopter, each with their own agenda driving their actions as the uncertainty hangs precariously in the balance.
