Amanda is a prestigious researcher in cardiovascular health who struggles to stay afloat in the sea of egos and economic interests that protects the greatest scientific deception of all time. The day she fails in her efforts to muzzle the booing of her conscience and loses her job, she hears an unusual siren's call from Cariño, a fishing village up on the north of Spain. As the dismissed doctor responds, she entangles the destinies of a dozen souls that will be turned upside down... or, perhaps, straightened out.
