context: Justin Quayle (Ralph Fiennes), a shy low-level British diplomat and horticultural hobbyist posted in Kenya, is one to avoid making a fuss until he learns that his wife Tessa (Rachel Weisz) was found dead in the veld. Tessa has been murdered at a crossroads along with her Kenyan driver. Her doctor colleague Arnold Bluhm (Hubert KoundÃ©) is initially suspected of her murder but is later found to have himself been murdered on the same day as Tessa. Various rumours abound that the two were having an affair; however, it is later revealed that Bluhm was gay.
  In flashbacks, we see how in London, Justin met his future wife Tessa, an outspoken humanitarian and Amnesty activist. He falls in love with her and she persuades him to take her back with him to Kenya. Despite their loving marriage, Tessa keeps from Justin the reason why she approached him in the first place - to investigate a suspicious drug trial in Kenya and expose it. When Tessa starts getting too close to uncovering the malpractices of an influential and powerful pharmaceutical company, she and her colleague are brutally murdered.
  As the mystery surrounding his wife's death unfolds, Justin becomes determined to get to the bottom of her murder. He soon runs up against a drug corporation that is using Kenya's population for fraudulent testing of a tuberculosis drug ("dypraxa"). The drug has known harmful side effects, but the corporation completely disregards the well-being of its poor African test subjects.
  Sir Bernard Pellegrin (Bill Nighy) is the head of the Africa Desk at the Foreign Office and he is the boss both of Justin and of the British High Commissioner, Sandy Woodrow (Danny Huston). In his investigations, Justin discovers that Tessa hid from him a report about the deaths caused by dypraxa, and he obtains an incriminating letter that Tessa took from Sandy.
  Justin confronts Sandy, who tells him that what Tessa wanted was to stop the dypraxa tests and redesign the drug. However, this would have cost millions of dollars and significantly delayed the drug, during which time other competing drugs would have surfaced. Pellegrin considered Tessa's report too damaging, and decided she had to be stopped.
  The company threatens Justin: he must stop his investigations or join his wife. In one instance, agents are sent to beat him up. Still determined, Justin takes a UN aid plane to the village where the doctor lives who provided Tessa with the clinical data behind her report. The doctor gives Justin a copy of the report, but the village is raided by armed tribesmen on horseback, and they are forced to flee from the carnage to the plane.
  Justin has the plane drop him off at the place where Tessa died. There he thinks about Tessa; he tells her memory that he knows all her secrets, that he understands her now, and that he is coming home. Shortly afterwards, he is killed in an organised hit.
  At Tessa's and Justin's funeral, Arthur Hammond (Tessa's close cousin and Justin's friend) reads the incriminating letter written by Bernard Pellegrin to Sandy Woodrow. In the letter, Pelligrin ordered the surveillance of Tessa, expressly to block her reports detailing the deaths caused by dypraxa. The company could not be held responsible for the dypraxa deaths if they never officially received the reports. The scandal having been revealed, Pellegrin leaves the funeral followed by journalists.
