Nicholas Van Orton, portrayed by Michael Douglas, is a highly successful and exceedingly wealthy investment banker. However, his remarkable achievements have come at a significant personal cost, resulting in estrangement from his ex-wife and only brother. He also lives with the haunting memory of witnessing his father's tragic suicide on his 48th birthday. On the day he turns 48, his younger brother, Conrad, played by Sean Penn, surprises him with an unexpected gift—a voucher for a mysterious "game" presented by a company called Consumer Recreation Services (CRS). Conrad insists that this experience will transform Nicholas's life for the better.
Initially skeptical about the gift, Nicholas puts off contacting CRS. Yet, a chance meeting with other club members who have had positive experiences with the game piques his curiosity, leading him to visit the CRS offices. Annoyed by the exhaustive psychological and physical evaluations he must undergo, Nicholas is ultimately informed that his application has been rejected. However, this is merely a facade, as the game has already begun.
As the events unfold, Nicholas finds himself entangled in a series of increasingly invasive and potentially criminal situations that jeopardize his business, reputation, finances, and safety. During this chaotic journey, he meets Christine, played by Deborah Kara Unger, a waitress who seems to be caught in the same turbulent web of the game. When Nicholas seeks law enforcement help, he is met with confusion, as the police find CRS's offices abandoned.
Conrad eventually comes forward to apologize, revealing that he too is a target of CRS's maneuvers. In desperation, Nicholas visits Christine's home, only to discover that it is a cleverly staged setup and that she is indeed an employee of CRS. As tension escalates, Nicholas's realization that he is being watched envelops him. A violent confrontation ensues as CRS operatives invade the apartment, leading Nicholas and Christine to flee for their lives. The situation intensifies as he discovers that CRS has drained his accounts, leaving him financially destitute, while Christine hints that some of his closest allies might be involved in the game.
In an alarming turn of events, after being drugged by Christine, Nicholas regains consciousness in a Mexican cemetery, where he must sacrifice his gold watch to return home. Upon his return, he finds his mansion vandalized by CRS. With no one else to rely on, he reaches out to his estranged wife, hoping to make amends. During their conversation, he uncovers that Jim Feingold, a CRS staff member who evaluated him, is a mere actor.
The stakes have never been higher as Nicholas confronts Feingold, forcing him to guide him back to CRS, where he ultimately takes Christine hostage, demanding to meet the organization’s leader. A climactic showdown on the rooftop ensues, with CRS operatives closing in. Just when Christine desperately tries to reveal the truth—that everything is a scripted game and his finances remain intact—Nicholas is engulfed in confusion and tension. In a shocking moment, he inadvertently shoots his brother Conrad, mistaking him for an enemy.
The chaos reaches its peak as Nicholas leaps from the roof, a chilling echo of his father's fate. As he plummets, his life flashes before his eyes, shattering through a glass ceiling and landing onto an enormous airbag. Soon, he finds himself surrounded by friends and family celebrating in a ballroom, realizing that it was all an elaborate setup orchestrated to help him embrace life.
Conrad is unharmed and explains that the entire game was a means of helping Nicholas break free from his self-imposed isolation. Overwhelmed with emotion, Nicholas eventually relaxes and starts to enjoy the unexpected reunion. Later, as he splits the game costs with Conrad—stunned by the expenses incurred—he spots Christine leaving the festivities. He seizes the chance to invite her to dinner, only to encounter an intriguing opportunity for a private coffee before she embarks on her next game assignment.
