Donald, a Nigerian, illegally entered Spain several years ago, but was extradited after getting involved with a gang of car robbers. Now he's back to fetch Teresa, the woman he loved and who had told him to come back for her. But three years have passed, and Teresa is now married to Antonio, with whom she has a young child. Frustrated with her small-town life, suffocating in the "sea of plastic" covering endless kilometers of tomato plants near Almería, Teresa dreams of a better life. Yet when Donald returns, she is afraid to take the first step. Donald, meanwhile, finds a job as a mechanic in an auto repair shop run by the kind and compassionate widow Carmen. The hard-working Nigerian makes friends with Carmen and with Antonio, who has no idea that Donald and his wife had an affair several years ago. Unfortunately, Donald provokes the jealousy of Paco, a drunk and racist who's in charge of finding workers to pick tomatoes. After Carmen rejects his marriage proposal, Paco begins to spread the rumor that Carmen and Donald are having an affair. And when Paco accidentally kills Carmen in a drunken rage, the townspeople are quick to pin the blame on Donald, who becomes fair game...
