On the front lines of a degraded emergency-care system in Sofia, Bulgaria, an over-extended, yet emphatically humane, paramedic crew hurtles frantically from one call to the next in a dilapidated ambulance: not quite the last one as implied by the title, but one of only thirteen servicing a city of an estimated two million people. Filmed primarily through the lenses of three dashboard-mounted cameras focused solely on the faces of the embattled trio making their rounds (patients are represented only by their off-camera dialogue and labored breathing), this unflinching observational documentary, directed by Bulgarian native Ilian Metev, unfolds in a series of real-time vignettes shot over the course of two years. The effects of perpetual struggle with broken-down communications systems, deteriorating infrastructure, false alarms, low pay, and the emotional toll of caring for Sofia's most vulnerable populations can be seen best in the deepening facial lines and gradually whitening hair of Doctor Krassimir Yordanov, apparently the only trained resuscitator left “in the whole of Sofia,” and in the pithy observation of his sweet-natured but no-nonsense right-hand woman, Nurse Mila Mikhailova, that “soon no one will want to do our job.” Winner of a France 4 Visionary Award for new talent at the 2012 Cannes Film Festival and Best Documentary at the 47th Karlovy Vary Film Festival in Prague, Sofia's Last Ambulance captures the quiet heroism and Sisyphean efforts of paramedics who form the thinnest possible white line in the combat against both systemic decay and human frailty.
