S2·E9 13 O'Clock

A woman and her boyfriend get hold of a cursed pocketwatch that lets the owner stop time for one hour (13 o'clock) if they kill a victim at a particular train station. Two street orphans witness one of the killings, and meet up with Ryan and Micki. By holding on to the couple, Ryan manages to enter their ""frozen hour"" and manages to get the watch away from them, leaving them trapped in time for eternity.
