BY MY SIDE follows Dominga, Fabiola and Maryuri, three young women struggling to survive in the Chureca, Central America's largest dump located in Nicaragua. Dominga has terminal Aids and tries to reestablish a relationship with her son that was taken from her at birth. Eleven year-old Fabiola is caught in a struggle between loyalty to her mother, and a group of evangelical Christians fighting for her to join a youth center far from the dump. At nineteen, Maryuri has ongoing health problems and is at risk of losing the second child she is expecting in the Chureca. In their quest for a better life, the three women will have to figure out whether their mothers are their best allies or unexpected foes.
