Israel is a writer and insurance salesman in the middle of a mid-life crisis who suddenly finds his world crumbling around him when, following some medical tests, his mother has to go into hospital in Vigo, where she lives. The nights are long as he waits for her to undergo tests and receive the results, and sleep doesn't come easily, but Israel has a lot to think about while he walks the corridors. Like Mario, his nine-year-old son, who he's raised as his own but who has started to ask questions about his biological father; or his mother's as-yet-unnamed illness, about her and her strength, her past as a single mother and about everything she went through in Israel's early childhood, like the strange death of her uncle Jaime; or about his brother, Alberto, on holiday in Cuba, who says he will come back straight away with Yanelis, an unknown woman with a suspiciously hoarse voice whom he claims is the love of his life.
