LOS ANGELES, Sept 21 — We’ll finally get to see Keanu Reeves back on the big screen soon enough in The Whole Truth.

The film which is written by Nicholas Kazan, focuses on a shocking murder trial and Reeves is on the case as defence attorney Richard Ramsay.

Renee Zellweger plays Loretta, the mother of a teenage boy (Gabriel Basso) accused of murdering his father(Jim Belushi). The case seems straightforward at first, but as the trial moves forward, Ramsay’s colleague (Gugu Mbatha-Raw) begins to suspect that not all is as it appears.

The official synopsis of the film reads: "Defence attorney Richard Ramsay (Reeves) takes on a personal case when he swears to his widowed friend, Loretta Lassiter (Zellweger), that he will keep her son Mike (Basso) out of prison. Charged with murdering his father, Mike initially confesses to the crime. But as the trial proceeds, chilling evidence about the kind of man that Boone Lassiter (Belushi) really was comes to light. While Ramsay uses the evidence to get his client acquitted, his new colleague Janelle (Mbatha-Raw) tries to dig deeper — and begins to realise that the whole truth is something she alone can uncover.”

The Whole Truth is set for release on October 21.
