It is Christmas. The Ibáñez family is a failure. They are broke, have no zest for life, and their family life is a disaster. When they are about to be evicted by the bank, they discover in their basement that someone dug a tunnel with the idea of robbing the bank across the street. With the help of Rufus, a retired veteran thief, the family decides to complete the tunnel and pull off the heist of their lives. However, living and working as a team will prove to be much more complicated than digging the last few meters of the tunnel. Between family conflicts, absurd situations, and a robbery where everything seems to go wrong, they will discover that at the end of that tunnel, something much more important than a millionaire’s loot awaits them.
