A captivating scene opens with a segment from the popular game show To Tell the Truth, set in the year 1977, where three individuals boldly claim to be the legendary Frank Abagnale Jr. (Leonardo DiCaprio), a mastermind who impersonated an airline pilot, a lawyer, and a doctor, all while swindling millions from unsuspecting victims across three continents—accomplishing all of this before he even turned 19 years old.
The narrative begins in 1969, where FBI agent Carl Hanratty Jr. (Tom Hanks) makes his way to a French prison to meet a sickly Frank Abagnale Jr.. In a daring attempt, Frank tries to evade being extradited to the US where he is wanted for an array of crimes. The story then flashes back six years prior, illustrating a poignant moment in Frank's life as a teenager in New Rochelle, New York. He resides with his father, Frank Abagnale, Sr. (Christopher Walken), and his mother, Paula. Caught up in a scheme, Frank Sr. cons a woman into lending them a suit for his son, which leads to a disastrous attempt to secure a bank loan, plunging the family into financial chaos and tension as they downgrade from a lavish home to a cramped apartment.
As the family strife escalates, young Frank discovers that his mother is having an affair with his father’s friend, spurring him to act out by impersonating a substitute teacher. The situation culminates in divorce, which propels Frank to run away, using checks his father had once provided. What begins as a desperate escape swiftly evolves into a series of audacious cons. Frank assumes the identity of an airline pilot and cunningly forges Pan Am payroll checks, allowing him to live lavishly in luxurious hotels and dine at high-end restaurants—essentially living a life of glamour funded by deceit.
Meanwhile, Carl Hanratty, the diligent yet often humorless FBI agent, remains hot on Frank's trail. Despite his superiors dismissing the case as unworthy of investigation, Carl becomes increasingly obsessed with capturing the elusive con artist. Upon locating Frank at a hotel, Carl attempts to apprehend him, only to be outwitted when Frank, posing as "Agent Barry Allen" of the U.S. Secret Service, cleverly escapes.
Amid his escapades, Frank tries to reconcile his shattered family. In a grand gesture, he invites his father to a posh restaurant and surprises him with a brand-new Cadillac. But the strained relationship between Frank and his parents continues to spiral as his mother remarries, leaving him heartbroken. As Carl intensifies his efforts to track down Frank, even utilizing yearbook photos to pinpoint his whereabouts, the chase takes a dramatic twist.
Fast forward to a year later, Frank has taken on an entirely new persona—this time as a doctor in Georgia, charming nurse Brenda Strong (played by Amy Adams) and weaving an intricate web of lies. Their evolving relationship leads to a marriage proposal fraught with complications, as Frank's past shadows their future. As the engagement party approaches, Carl's relentless pursuit reaches its zenith, culminating in an emotional confrontation where Frank reveals the truth to Brenda just as he faces impending capture.
In a last-ditch effort to evade the authorities, Frank crafts a new disguise, impersonating a Pan Am recruiter, which leads him directly into Carl's clutches once more. This time, Frank is brought to justice, eventually imprisoned after a whirlwind of global cons and deceits. Over the years, an unlikely bond forms between Frank and Carl as they collaborate to catch other forgers.
By the conclusion, amidst all the thrills and struggles, a touching reveal shows that Frank has found happiness and stability in life, now married for over 26 years, raising three sons in the Midwest, and maintaining a solid friendship with Carl, proving that even an ex-con can forge a new path forward.
