Hired to locate a missing witness in a murder trial, Ross does just that, but regrets it. Working for a defense attorney, Ross tracks down a fleeing witness, Murphy, and by so doing, unwittingly the man's murder by Starns, a thug posing as a friend of Ross' client. Ross is desperate to get his new evidence to the courtroom where the trial is underway, but first must elude two men who are out to silence him. Wounded in the chase, Ross solicits the aid of two runaway hippies.
