Two best friends who are in danger of being separated forever run away from home. The friendship between two children is threatened by their parents' differences. Malu is from an upper-class family and her single mother does not want her to play with Jorgito, as she thinks his background coarse and commonplace. Jorgito's mother, a poor socialist proud of her family's social standing, places similar restrictions on her son. What neither woman recognizes is the immense strength of the bond between Malu and Jorgito. When the children learn that Malu's mother is planning to leave Cuba, they decide to travel to the other side of the island to find Malu's father and persuade him against signing the forms that would allow it.
