KING OF THE DEAD
LOGLINE
A lonely repairman discovers a door where the dead can be reclaimed at the cost of twenty-five living years per hour; after bringing four family members back, he spends a lifetime trying to defeat the one loss the bargain cannot undo.
The exchange rate is twenty-five years of your life for one hour of theirs. A repairman runs the numbers anyway, four times, then spends everything he has left on the one repair the door will not make.
