Will Colson – the young man who is appointed the assistant driver on the locomotive going in Milzburg . As the driver Frank Barnes – the skilled expert works with 28-year length of service which watchfully concerns to the new workmate which preparation is limited only to 4-month courses. The difference in experience of professional activity of the driver and his assistant smoothes out identical problems in private life a little: both Frank, and Will have not the best times.
While the locomotive under their management follows to the destination, in the north of the neighboring state there is a force. As a result of adverse combination of circumstances one of trains remains without driver and gathers speed. At some point Will and Frank by miracle avoid collision with the uncontrollable train, but to them the order of a message of "fugitive" to the following station as special services can't execute operation on his interception arrives. Difficult change is necessary to workmates.
