Originally being from English descent, Sam was taken on board by the Americans under a private organization to boost their military efforts, and was stationed in Chernogorsk when
the wave of infected hit the city and caused US forces to flee, she was among the foolish to stay with the CDF and retreat towards the countryside. She was then chosen there to fly
CAF helicopters in search of refugees in lost areas, however, something during this mission went horribly wrong. Her helicopter was shot down by a group of rioting civilians when
scouting, and while falling she accepted death, however, it never came.
She managed to survive the crash by a thread of life. Sam owes this thanks to a farmer who had saved her from the wreckage and woke her from unconsciousness with a dose of
epinephrine. By the time she had fully awoken and recovered within the small ranch house her saviour was based in, the CDF had already started retreating and there was no hope
for her leaving the province.
Sam dedicated herself to still do her duty as military and save as many survivor lives as possible, along with help them on their path of surviving. She has major resentment for
Infected and tends to avoid them, find ways around them, and kill them if needed. She does resort to hostile actions if provoked, but hardly ever provokes it herself.
