Season 1 · Episode 7
To carry out the biggest heist in history, a mysterious man called The Professor recruits a band of eight robbers who have a single characteristic: none of them has anything to lose. Five months of seclusion - memorizing every step, every detail, every probability - culminate in eleven days locked up in the National Coinage and Stamp Factory of Spain, surrounded by police forces and with dozens of hostages in their power, to find out whether their suicide wager will lead to everything or nothing.

Widely used in everyday speech to mean an unresolved detail or potential weak point that could unravel a larger plan or situation. From the nautical image of an untied rope end. Carries a tone of urgency or risk.
Originally a firearms term meaning fired at extremely close range. In everyday speech it describes something said or done suddenly and directly, with no preamble or softening. Implies the receiver was caught off guard.
Extremely high-frequency dismissive reassurance in everyday Castilian speech. Used to wave off an apology or defuse tension. The tone ranges from warm and genuine to slightly impatient depending on context. Not a literal claim that nothing happened.
One of the most versatile and frequent exclamations in informal Castilian speech. Expresses surprise, frustration, admiration, or sudden realization. Its literal religious meaning is entirely absent in casual use. Strength varies with tone; can be affectionate between close friends.
Intensifier expressing exasperation or strong demand for an explanation. Common in heated or emotionally charged exchanges between people who know each other. The anatomical root is felt as a swear word but its pragmatic force is purely emphatic.
Idiomatic expression meaning to take a firm, unambiguous stand to silence opposition or impose one's will. The image is of a literal fist on a table to demand attention. Used in both professional and personal confrontational contexts.
From the image of tuning pegs on a stringed instrument, tightening them increases tension. Means to increase pressure on someone to force compliance or action. Common in negotiations, investigations, and management contexts.
Borrowed from French but fully integrated into Castilian everyday usage. In general speech it means a private face-to-face encounter. In the specific context of the prison system, it refers to the supervised private visits inmates receive. The dual register, sophisticated and carceral, can be exploited for ironic effect.
