Ifemelu, a young, beautiful, self-assured woman raised in Nigeria, fell in love as a teenager with her classmate Obinze. Living in a military-ruled country, they each depart for the west, with Ifemelu heading for America, where, despite her academic success, she is forced to grapple for the first time with what it means to be black. Quiet, thoughtful Obinze had hoped to join her, but with post-9/11 America closed to him, he instead plunges into a dangerous undocumented life in London.
