Tim Balfour has returned to America from Italy after his parents died in an auto accident there. His grandfather (Otto Kruger) is bedridden from the aftermath of a heart attack. His uncle doesn't like or trust young Tim because of his slacker ways and his equally slacker friends.
Up to the present, the sum total of Tim's offences consists of him having a couple of moving violations and being chronically absentee from his skate job at the family business. But one night his delinquent buddies decide to rob a store and Tim, although he protests, winds up being the driver of the getaway car. He is told by one of his two associates that he'll need to get money so that "Chick" and his friend can hide out or else they'll say he was the ringleader in the robbery. The price rises to two thousand dollars. Tim can't go to a relative, so he asks the Balfour housekeeper for the money, lies about the severity of the trouble he is in, and even lets her steal the money from his grandfather for him. But Tim and Chick get into an argument when he goes to give the money to Chick, and Tim shoots at Chick and drives away leaving behind his gun. Later, Chick is found dead, shot to death as Tim feared, but shot in the back, while Tim shot when Chick was facing him. Tim is arrested for murder and Balfour company attorney Perry Mason is on the case.
Complicating factors include Tim's grandfather wanting to give TIm a piece of his company in his will and TIm's uncle vowing he'll do anything to stop it. Also, where did that pesky accomplice of Chick's go to? He seems to disappear in thin air after he robs the store.
Lots of people seem to really hate hate hate the defendant in this case. I admit it's hard to feel sorry for him when he is so sorry for himself, and that Johnny Washbrook's performance as Tim Balfour is hardly subtle, but then it's not hammy either. I looked up Mr. Washbrook's acting credits, and it looks like he was primarily a child actor who aged out of such parts by age 20, the year after this episode.
Also note that Billy Benedict is playing a drunk old man who may or may not have been run over by Tim. Benedict has acting credits that go back to the 1930s and was in the Monogram Bowery Boys films. He is only 46 when he made this, but looks much older.
