With two of the their companions getting sicker by the minute the group flees the dead infested town. After diverting their journey down a set of train tracks it becomes clear that they can't travel with their sick comrades and must find shelter. Polar and Seal scout ahead and with luck find a train sitting in the middle of nowhere. While Polar stays with train and its conductor Seal runs back to the group that have become overrun with the Seconds. A daring adventure and risk taking is the only way they will survive. Polar's mechanical skills prove invaluable.

Thanks for watching!
