When Harry was on the police force, he spent six months looking for Don Yorkfield, who was a hit and run suspect. The victim was a member of the mob. At the time, Yorkfield's wife did not want to help Harry find her husband. Now, the tables are turned and she goes to Harry for help. Her daughter Shelly needs a kidney transplant and Dad's blood type is the same as hers. Harry goes back through his old case file, gets new clues from the now cooperative wife, and wins over young Shelly, all the while dodging two mob hit men. Harry eventually finds Yorkfield, but that's not the end of the drama.
