Un plan perfecto is a Spanish family comedy set at Christmas, when the Ibáñez family is on the verge of financial collapse and facing eviction. Their fortunes seem to change when they discover a tunnel in their basement that was apparently dug to reach the bank across the street.
With help from a retired thief named Rufus, the family decides to finish the tunnel and attempt the robbery themselves. The premise turns family dysfunction into the engine for a comic heist, combining a holiday setting with a cast of Spanish comic performers.
Un plan perfecto opened in Spanish cinemas in September 2026, while digital availability depends on the Spanish and international release strategy.
