The King Is Alive (2000)

"As the sand shifts... madness nears."

Stranded in the heat of a barren African desert, eleven bus-passengers shelter in the remnants of an abandoned town. As rescue grows more remote by the day and anxiety deepens, an idea emerges: why not stage a play. However the choice of King Lear only manages to plunge this disparate group of travelers into turmoil as they struggle to overcome both nature's wrath and their own morality.
