If the armadillo hadn't crossed the moonlit road at that specific moment in 1967, the newlywed couple would not have died in a car crash.

Cascading anomalies proliferated around that moment on the moonlit highway and the orderly flow of Time would never be the same ... if it ever was to start with.
