Frank Wyatt, played by Emilio Estevez, is a devoted husband and father who steps out for a night with friends to attend a boxing match in the bustling streets of modern-day Chicago. Accompanied by his pals, Mike Peterson, portrayed by Cuba Gooding Jr., and Ray Cochran, played by Jeremy Piven, they embark on this anticipated adventure aboard Ray's extravagant RV, which he is evaluating for business purposes. When another friend backs out last minute, Frank extends an invitation to his brother John, enacted by Stephen Dorff, completing their group for the night.
As they head to the city, the group is soon caught in a frustrating traffic jam, prompting John to confront another driver in anger. Looking to escape the gridlock, Ray decides to veer off the main thoroughfare into a dilapidated neighborhood in search of a quicker route. In a shocking turn of events, their journey takes a sinister detour when they run over a man named Teddy, played by Michael DeLorenzo, who is found injured in the street. They bring him into the RV, only to discover he has been shot and is carrying a bag filled with money.
The tension escalates when Mike hears police sirens nearby, prompting Frank to hastily take control of the RV in an attempt to evade the authorities. However, their misfortune worsens as their vehicle is struck by another car, forcing it into a narrow alleyway where it becomes lodged between two brick walls. Just as they think they have caught a break, a gang led by the ruthless Fallon, brilliantly portrayed by Denis Leary, appears. They overhear the gang discussing their suspicion that Teddy has crossed them, leading to a fatal confrontation where Fallon coldly executes Teddy, stating bluntly > "No witnesses."
Realizing their lives are in imminent danger, Mike, Frank, and John make a hasty escape, breaking the RV's windshield and setting it ablaze before fleeing. The four friends seek refuge in a nearby railyard, boarding an empty train as Fallon and his crew scour the area in search of them. Inside the train, they encounter a group of seedy homeless individuals, led by a ringleader who opportunistically blackmails them for money in exchange for silence about their whereabouts. Each friend sacrifices something valuable, but tensions escalate, and when one of the homeless men, Buck, lays claim to Mike’s college jacket, the situation spirals as Fallon's gang closes in.
A gunshot rings out, tragically claiming Buck’s life and inadvertently revealing Frank’s identity to Fallon, who now knows where he lives and who his family is. The friends continue their frantic sprint for survival, ultimately finding refuge in an apartment building, where they hope to alert the police. However, their safety is short-lived as Fallon and his gang terrorize the building's residents in pursuit of them. In a desperate bid for escape, the group retreats to the rooftop, where fears and tensions culminate in a heartbreaking sacrifice when Ray stays behind, believing he can negotiate with their pursuers, only to be murdered by Fallon.
With nowhere left to run, Frank and the remaining friends devise a counterattack, courageously pursuing their own path to survival. A confrontation results in them empowering themselves—Mike seizing a gun and eliminating Sykes, Fallon's number two. But as they exit the sewers, their luck takes another downturn: while trying to flag down a bus for help, they are misidentified, leaving them stranded. Mike takes desperate measures to trigger an alarm at a grocery store, but before they can catch a break, Fallon's gang catches up with them once more.
In a tense showdown, Mike suffers a gunshot wound to the stomach while trying to aid John, who is also injured. Frank bravely leads the ruthless Fallon away from his wounded friends, initiating a final struggle that ends with him pushing Fallon to his demise down a flight of stairs. The film concludes with the police piecing together the chaos in the aftermath, as Frank’s wallet is recovered, hinting at the potential for survival for Mike and John as they are wheeled away for medical help.
