Northern Michigan tornado, Sadie Wixom is left with only her father and grandfather to guide her through the pitfalls of young adulthood.

Hundreds of miles away in western Saskatchewan, Stefan Montegrand and his Indigenous family are forced off their land by multinational energy companies and flawed treaties. They are taken in temporarily by Sadie's aunt, a human rights activist who heads a cultural exchange program.

Stefan, whose own father died in prison while on a hunger strike, promptly runs afoul of local authority, but Sadie, intrigued by him and captivated by his story, has grown sympathetic to his cause and complicit in his pushback against prejudiced accusations.

Their mutual attraction and struggle for equilibrium is stymied when Stefan's older brother, Joachim, who stayed behind, becomes embroiled in the resistance, and Stefan is compelled to return to Canada. Sadie, concerned for his safety, impulsively follows on a trajectory doomed by cultural misunderstanding and oncoming winter.

Let Evening Come is the love story between the son of an Indigenous family displaced from their ancestral home on the Tar Sands of Canada and a motherless farm girl from Michigan. Together they combat suspicion and bigotry on both sides of the border and the cultural differences that separate them.
