The death of Ernesto Martel (José Luis Gómez) sets off a chain of events that forces one man to come to terms with his past. Before he went blind, Harry Caine was Mateo Blanco (Lluís Homar), a film director who often worked with Ernesto. Ten years ago, Ernesto and Mateo's friendship became a battle for Lena (Penélope Cruz), Ernesto's mistress and Mateo's secret object of affection. When the former recruits his son (Rubén Ochandiano) to spy on the latter, things quickly spiral out of control.
