Those in tune with the complexities of Argentine politics will have the best understanding of the subversive, satirical points made in this off-beat low-budget parable. Those unfamiliar with the countrys history and problems, but who have a taste for intellectual and academic filmmaking, will still find much to enjoy. The story is set beneath Buenos Aires, deep within its labyrinthine subway system, and centers on a train containing 30 riders that has mysteriously disappeared (much like political dissidents tend to vanish in Argentina). The subway officials are greatly troubled and so call in topographer Daniel Pratt to help them find it. Unfortunately, the tunnel system is so vast and complex, that Pratt must find his mentor Hugo Mistein for help. Unfortunately, he too has disappeared. Fortunately, he left the system plans behind and as Daniel studies them, he comes to the awful realization that the train, which can be heard but not seen, has somehow become trapped in a fourth dimension. His findings attract the attention of local bureaucrats who are too rigid and pragmatic to accept Pratts outlandish theory. This causes the determined Pratt to board a train that contains an exact replica of Mistein and see for himself exactly where it goes. The film was adapted from A.J. Deutschs short story A Subway by Moebius. ~ Sandra Brennan, All Movie Guide
