I due carabinieri

[2][3][4] Marino (Carlo Verdone) and Glauco (Enrico Montesano) enlist with the Carabinieri in order to change their lives and find stability and maturity within the military discipline of the armed force.

During training, they also find a third partner in Adalberto (Massimo Boldi), sickly heir to an affluent family, also pursuing a law enforcement career in an effort to grow more independent from his over-protecting parents.

The trio share various adventures until graduation, and then begin to take part in real missions, with happy-go-lucky and carefree attitude, to the point of simulating a fake police raid to a clandestine brothel in hope to get free service, partaking to confiscated cocaine, flirting with some women that are victims of phone molestations.

She reciprocates Glauco's love but only has brotherly affection for Marino, who feels therefore betrayed in his imaginary relationship with the woman, and attacks violently the colleague.

In the end however harmony is recovered, when Glauco risks his life to save the old friend and a group of boy scouts which had been taken hostage by a madman on the same train.
