Miracle on the Precipice (1970)

Inspired by John Bunyan's The Pilgrim's Progress, the Lightly family struggles with a rebellious son, a selfish adopted daughter, an overworked mother and an out of work father. When they leave for a mountain park to decompress and try to rebuild their once joyful family, tragedy strikes and the Lightlys begin a fight for survival that challenges everything they know about themselves and their beliefs.
