The film stars Keanu Reeves, Gabriel Basso, Gugu Mbatha-Raw, Renée Zellweger, and Jim Belushi.

Defense attorney Richard Ramsay works the case of 17-year-old Mike Lassiter's alleged murder of his wealthy lawyer father Boone, a professional friend.

Ramsay employs young, talented lawyer Janelle Brady, daughter of another professional friend, as his associate after she leaves a career in corporate law.

The police officer who first responded to the call testifies that at the scene of the crime, Mike muttered "I should've done it long ago", and she and the chief detective affirm that his fingerprints were found on the murder weapon.

Under questioning by Janelle, the attendant admits to covering up her extramarital affair with the co-pilot and potentially spending too much time in the cockpit to confidently deny any unusual interactions between father and son.

[11] Brian Tallerico of RogerEbert.com criticized the film for being "sterile and flat" and felt surprised that director Hunt was in charge of a "lackluster production" that follows the "Grisham playbook", concluding that: "Ultimately, there's nothing offensively bad here—other than a waste of talent who should be doing better work—but it's so forgettable that you'll have trouble remembering if you saw it or not when you scroll past it on cable in a few months.

[13] Jeannette Catsoulis of The New York Times called it a "claustrophobic courtroom procedural" that's "drably photographed and generically framed" and tells a "soulless and poorly dramatized" plot that leaves its two main leads with little room to shine from a bare-bones script.

[14] Robert Abele of the Los Angeles Times was critical of the film's "general listlessness" and the "regrettably mannered acting" from the cast causing the story to lack tension.

Club's Noel Murray gave the movie an overall C+ grade, writing that "The Whole Truth is a moderately clever, reasonably entertaining courtroom drama, which is only a problem given the talent involved with bringing something this middle-of-the-road to the screen.
