Pray for the Wildcats (1974)

They're off on a wild motorcycle trip into hell... a bully... a coward... a survivor... and a man who faces his own death and finds a courage he never knew he had.

Three ad agency executives are pressured into taking a motorbike trip to Baja by a big-ticket client. Along the way, the client is spurned by a young woman whose boyfriend sticks up for her. The client later disables their van, leading to their deaths in the desert. When the executives piece together what has happened, it leads to a showdown.
