In the spring of 1992, a serial killer cut a swathe through the Mid West with six victims across three states, shot execution style. The victims all worked in small stores just blocks from I-70. Phelps and Kelly take a long trek across the Midwest to investigate the unsolved murders on this lonely stretch of highway.
Four young girls go missing in Massachusetts and Connecticut. Some turn up dead, some are never seen again. Phelps and Kelly investigate the murders which are decades apart but with one thing in common: blonde hair and blue eyes. But are they connected in another way? Are they victims of the same serial killer?
