A dramatization of John Reed's newspaper accounts of the Mexican Revolution. Considered the first real film in Mexican cinema to be made on the Mexican Revolution.

Carlos is a young student, just 21. Nice or annoying as he likes, enjoys provoking and transgreding. In the night he goes out to meet his friends in the Kronen, a bar. Every situation can be taken a little farther. There are no limits, no accepted barriers. And more each time, each adventure is chained to the next, as if it were a continuous night. A long description of people: grandfather, parents, sister, girlfriend, friends. And, among that, the obscure will of living every minute as if it were the last one. But something which happens puts Carlos and his friend against a reality they have been trying to ignore.

Juan is now in his fifties, has a protruding belly, dyes his hair gray and lives alone with a cat who has urinary problems, but despite this, women still find him attractive.
