Four women meet while riding buses across West African borders, starting in Dakar and traveling to Lagos through Bamako, Cotonou, and Ouagadougou. Despite the gorgeous landscapes of the Atlantic coast and the Sahel, not everything is beautiful: they undergo car breakdowns in the stifling heat, face highway robbers, and endure fights between passengers. But their worst fears are realized in the liminal space of the border itself, where they witness great corruption, violence against women, and dangerous traffic. To survive, the women must stick together and take care of each other: the consequences of this trip will change their lives.
