Here's the rephrased section:

In the midst of the tumultuous American Civil War in 1863, a group of Confederate soldiers are carrying a gold bullion as payment for their services. However, their journey is abruptly cut short when they're ambushed by an enigmatic highwayman wielding futuristic technology and automatic firearms. The unexpected attack leaves the soldiers lifeless and scattered across the terrain. The mysterious marauder seizes the golden treasure and vanishes into thin air, leaving behind a trail of confusion and uncertainty.

Fast-forward to 1994 in Washington D.C., where the United States government has established the Time Enforcement Commission (TEC) to regulate the misuse of time travel technology. The agency has discovered that the same gold bullion is linked to recent arms deals, sparking concerns about its potential impact on the timeline. As a result, the TEC is tasked with detecting "time ripples" and preventing them from affecting the present. Senator Aaron McComb (Ron Silver) lends his support and oversight to the commission.

Meanwhile, Officer Max Walker (Jean Claude Van Damme) finds himself at the center of a mysterious web when he's offered a position as a TEC agent. As he navigates his new role, Walker's personal life takes an unexpected turn when he stops a purse snatcher at a local shopping mall and reunites with his wife Melissa (Mia Sara). Their evening takes a romantic turn as they return home to their lavish residence. However, the tranquility is short-lived as Walker is suddenly attacked in his own home by the same group of suspicious individuals he encountered earlier. The chaos culminates in tragedy as Melissa meets her untimely demise and their house is reduced to ashes.

Ten years later, Walker has become a seasoned TEC Agent, tasked with apprehending his former partner Atwood (Jason Schombing) for exploiting the 1929 Wall Street crash. As Walker interrogates Atwood, he uncovers a web of deceit that reveals Senator McComb's involvement in the scheme. Terrified by the threat of having his ancestors targeted and erased from existence, Atwood attempts to take his own life by jumping from a great height. Walker intervenes, saving Atwood but ultimately failing to extract any valuable information. The TEC agency sends Atwood back to 1929, where he meets his untimely demise once again.

As Senator McComb arrives at the TEC agency, Walker greets him with an air of familiarity, hinting at his awareness of the senator's underhanded dealings and financial machinations. McComb's demeanor turns cold as he exits the facility, instructing his aide to take care of Walker, but the operative proves a formidable foe, dispatching two would-be assassins in a brutal display of martial arts prowess.

Undeterred by this close call, Walker continues to dig into McComb's corruption, only to be partnered with agent Sarah Fielding (Gloria Reuben), whose seemingly innocent partnership belies her true allegiance. As they travel back to 1994 to investigate a pending ripple, Walker finds himself in the midst of a tense confrontation between young Senator McComb and his business partner Jack Parker, who is offering to buy out McComb's share of their company.

However, the scene takes a dramatic turn as older McComb appears from 2004, warning his younger self about the impending profits to be made from a revolutionary computer chip. As tensions escalate into violence, Walker finds himself double-crossed by Fielding, who reveals her true loyalty lies with McComb. The senator brutally dispatches Parker and wounds Fielding before attempting to kill Walker, ultimately managing to escape back to 2004.

Upon his return to the present, Walker discovers that McComb's influence has grown exponentially, with the senator now owning the computer company and enjoying a seemingly insurmountable lead in the presidential race. The TEC agency is being dismantled due to budget cuts, and Fielding's existence appears erased from the record books.

Realizing the gravity of the situation, Walker hijacks McComb's time machine prototype, aided by Commander Matuzak (Bruce McGill), who sacrifices himself to ensure Walker's escape. As Walker once again finds himself in 1994, he locates a wounded Fielding in the hospital and convinces her to testify against McComb.

However, in his quest to prevent further tragedy, Walker uncovers a devastating truth: Melissa is pregnant, and her death will occur that very night. With a newfound sense of urgency, Walker decides to alter the course of events, only to find himself framed for Fielding's murder upon returning to her hospital room.

As Max Walker ventures back to the mall where his serendipitous encounter with Melissa transpired, he finally tracks her down and successfully convinces her of his extraordinary claim: that he is a temporal traveler from the future. Moreover, he discovers that the trio of thugs who brutally attacked him are none other than the henchmen of corrupt Senator McComb, dispatched to eliminate him before he joined the secretive organization known as TEC.

That fateful evening, McComb's goons launch a brazen attack on Walker's residence, only this time his older self is waiting in ambush. Without the younger Walker being aware of it, his more seasoned counterpart seamlessly integrates himself into the fray, together with Melissa, to repel the nefarious intruders. The ensuing battle leaves the younger Walker wounded but ultimately victorious, as they manage to subdue their assailants.

As McComb's grip on reality begins to slip, he takes Melissa hostage and sets a ticking time bomb, his malevolent intentions foiled only by the timely intervention of his older self. With calculated precision, McComb shoots Melissa just as the younger version of himself appears, having been duped into coming to the house by a cleverly crafted fake message from Walker. The ensuing chaos culminates in an otherworldly spectacle as the two Walkers merge into a writhing, screaming mass that ultimately disintegrates, adhering to the fundamental principles of time theory – where no two individuals can coexist through physical contact.

As Walker carries the wounded Melissa to safety mere moments before the bomb detonates, destroying his home in the process. He then tenderly places Melissa beside her younger self and flees the scene as the local authorities and emergency responders arrive on the scene. With his mission accomplished, Walker returns to 2004, correcting the timeline and ensuring that TEC remains intact, Fielding and Matuzak continue to thrive, and McComb's malevolent presence is erased from existence – having "vanished" a decade earlier.

As Walker reenters his home in the present day, he is met with a heartwarming surprise: Melissa is alive, and their nine-year-old son awaits him at the threshold. As they sit down for dinner, Melissa shares a life-altering announcement with Walker – one that hints at another addition to their family on the horizon.
