Dypraxa was a new vaccine being tested by a pharmaceutical company on local populations in Kenya without proper disclosure or ethical oversight. The drug caused numerous fatalities among those tested, and the company concealed these deaths to push the vaccine through approval. Tessa discovered this cover-up and was killed for exposing it.

Foreshadowing: The film shows Tessa researching documents and talking to local communities about illnesses.

Justin grew suspicious because Tessa's humanitarian passion seemed to outweigh her romantic feelings toward him. After their child was lost, their relationship deteriorated, and Tessa increasingly focused on her advocacy work. Justin began to believe she married him specifically to gain access to the diplomatic world and use his position to champion refugee causes rather than out of genuine love.

Foreshadowing: Their first meeting shows Tessa challenging Justin's views, and flashbacks reveal her prioritization of causes over their marriage.

Justin suspects Tessa was having an affair with Sandy Woodrow, who worked for the pharmaceutical company involved in the Dypraxa trials. However, the film leaves this ambiguous, it's unclear whether the affair was real or something Justin imagined due to his growing distrust. Sandy is shown to be complicit in the unethical drug testing, motivated by potential profits.

Foreshadowing: Scenes show Tessa meeting privately with Sandy and Justin becoming increasingly jealous and paranoid.

Arnold Bluhm was a fellow humanitarian worker who was helping Tessa investigate the Dypraxa scandal. He was murdered in Kenya, likely by the same forces behind Tessa's death, to silence anyone who knew about the pharmaceutical conspiracy. His death intensified Justin's determination to uncover the truth.

Foreshadowing: Tessa and Arnold are shown working together on the investigation before their deaths.

Bernard Pellegrin was a former government minister and Justin's ex-boss. Justin suspects he was involved in the conspiracy surrounding Dypraxa, using his government connections to help the pharmaceutical company conduct unethical trials. Pellegrin represents the corruption at the highest levels of government that Tessa was trying to expose.

Foreshadowing: Justin recalls his past working under Pellegrin and notices suspicious connections.

Justin died after returning to Kenya, going to the site where Tessa was killed. The film depicts him walking toward local gunmen, and while it's ambiguous whether he was killed by them or took his own life, whispers of suicide circulate. Tessa's cousin reveals a letter Justin wrote before his death that exposed the corruption he uncovered.

Foreshadowing: Justin expresses resignation and acceptance of his fate throughout the investigation.

Before dying, Justin wrote a letter detailing the corruption he uncovered involving the pharmaceutical company, government officials like Bernard Pellegrin, and the unethical Dypraxa trials. Tessa's cousin revealed this letter at Justin's funeral, sparking public outrage against the corporation despite their stocks rising afterward.

Foreshadowing: Justin spends his final days writing and documenting his findings.

No justice was served. Despite the public outcry generated by Justin's letter, the pharmaceutical company's stocks actually surged afterward. The film ends with the bleak realization that those in power, government officials and corporations, remain insulated from consequences while ordinary people suffer. Justin and Tessa's deaths ultimately achieved little tangible change.

Foreshadowing: The film's tone remains dark throughout, with corruption prevailing at every turn.
