Bilbao Blues (1986)

Beatriz is an attractive young lawyer who enjoys an enviable position thanks to the influence of her father, a prominent businessman. Lucas, a young man with a rather shady past, is struggling to emerge from the unfavorable situation in which life has placed him. When Lucas is arrested with a stash of adulterated cocaine, he becomes a client of Beatrice. He has hidden the pure cocaine with the intent to share it only with his associate Uriarte; and to do so he has had to deceive another one of his accomplices, making him believe that the business has failed.
