Plot summary

Wheelchair-bound and distraught by the accidental deaths of his wife and his little daughter, reclusive tech wizard Joaquín spends his days fiddling with computers in the basement of his large, dilapidated house with only an aging, sickly dog for company. After reluctantly renting out a room to exotic dancer Berta and her silent daughter Betty, Joaquín hears muffled voices coming through the wall and discovers that a criminal gang is digging a tunnel right under his basement to commit a bank heist. Joaquín crafts a plan to ruin their plot, but sudden revelations will drag everyone into a deadly cat-and-mouse game with an uncertain outcome.—Paulo Mendes
