The main conflict in Alex Agyei-Agyiri's Unexpected Joy at Dawn is corruption. The novel is set against the backdrop of the mass expulsions of foreigners in both Ghana and Nigeria - the Aliens Compliance Order in Ghana and the "Ghana Must Go" decree in Nigeria. While these political events drive the plot, the underlying conflict that pervades the narrative is the widespread corruption in both societies.

Corruption manifests at every level of the novel's world: government officials exploit their positions for personal gain, border officials extort migrants, police and soldiers abuse their authority, and ordinary citizens take advantage of the chaos to seize the property of expelled foreigners. The suffering of characters such as Nii Tackie and Mama Orojo is deepened not merely by the expulsion orders themselves but by the corruption of those charged with implementing them. The system that should protect citizens instead preys upon the vulnerable.

While love (the bond between separated family members) and health concerns appear in the novel, they are secondary to the pervasive corruption that constitutes the central source of conflict. Greed is related to corruption but is not as comprehensive a description of the novel's main conflict.
