In a wild comedy, we meet Fletcher Reede, a successful lawyer who has become addicted to lies. His life takes a turn when, on his birthday, his young son Max, frustrated by his father's constant neglect, makes a wish: that Fletcher cannot tell a single lie for 24 hours. Faced with fears, trials, and an impending custody battle, Fletcher is forced to confront harsh reality.
Suddenly, the man who has made a living manipulating the truth finds himself with his hands tied. In his race to succeed in an important case, his usual lies turn into a trap, exposing not only his capabilities as a lawyer but also his relationship with his son. Each comedic situation becomes more hilarious as he tries to navigate a courtroom where honesty is his worst enemy.
Over time, Fletcher, masterfully portrayed by Jim Carrey, begins to rethink what it means to be a good father and a good person, all while dealing with his son's mother, played by Maura Tierney, who is keeping a close watch on each of his moves. The movie not only evokes belly laughs but also leaves a heartfelt message about the importance of sincerity and authenticity in relationships, all wrapped up in a chaos of absurd situations and unexpected twists. A true feast of laughs and emotions!
