On New Year's Eve in 1987, lightning kills Nate's and Danny's mother. To deal with the loss and make sense of a world seemingly governed by chance, their distant and eccentric father creates the Nicotine Gospel.

"According to him, an eight by five cardboard box containing somewhere near twenty machine-made cigarettes would tell you all you needed to know about a man."

The boys throw themselves into the lessons to be close to their dad, but as nate grows up and begins to understand how strange the family gospel (and their father) truly is, he starts to worry. While Nate excels at school and finds ways to escape their father's neglect and the increasingly ramshackle house in Durban, Danny seems to revel in courting danger and death.

Decades later, upon learning of their father's death, Nate and Danny, long estranged, decide to drive from Durban to Cape Town to attend the funeral. On the journey, they must confront each other and their troubled past to find a way forward.
