During one of the first heavy snows of the winter, on the
Interstate outside the Twin Cities, Rushmore McKenzie is
behind a truck behaving erratically when the man in the
truck bed dumps a body out onto the road, right in front of
McKenzie's car. McKenzie avoids hitting the body, a bound
woman who is just barely alive, but his stopped car in the
middle of the road starts a chain of accidents, resulting in
a thirty-seven car pile-up. By the time the time the police
arrive, and the EMTs and ambulances have taken care of the
immediate injuries, the truck is long gone.
The injured woman awakens with no memories--not of the
accident, not of anything--and is labeled by the police as
Unidentified Woman #15. With few leads, the detective in
charge, McKenzie's former partner and old friend Bobby
Dunston, turns to McKenzie for a favor. Now McKenzie has to
try to identify the grievously injured woman, find out who
tied her up and dumped on the freeway to die. And why.
