The ensemble cast features Arturo Valls, Raúl Cimas, Natalia de Molina and Neus Asensi, among others.

The plot tracks the interactions of a group of survivors from a disaster (they were trapped in a tunnel for 15 days) after their rescue.

Jordi Costa of Fotogramas rated The Tunnel Gang 4 out of 5 stars, assessing it to be reminiscent of Italian post-war comedies, and considering that, rather than featuring deliberate comical one-liners, the comedy value of the whole is relentless by relying on an "absolute confidence in a perfect and dedicated cast and a great ability to know in what voice and tone the everyday and even the trivial will turn out to be hilarious".

[1] Beatriz Martínez of El Periódico de Catalunya scored 3 out of 5 stars, underscoring the film to be "a little eccentricity, a rara avis out of the menu", surprising due to the "strangeness of its proposal".

[11] Raquel Hernández Luján of HobbyConsolas scored 55 out of 100 points ("average"), deeming The Tunnel Gang to be a "strange comedy tinged with drama", highlighting the narration of what happened in the tunnel as the best thing about the film, while negatively assessing the excessive number of characters, the "irregular" pace and "certain lack of wit in the dialogues".
