This episode is interesting because it stars Fred Grady (from "My Three Sons") as well as Flora Plumb, the older sister of Eve Plumb from "The Brady Bunch". It also shows the way the mob infiltrates legitimate businesses.
When the episode begins, John and Yvonne (Grady and Plumb) are walking along the beach and wander onto a government storage depot. They soon are caught by a guard and they run. In the process, they knock over some barrels of chemicals and they ignite...badly burning the guard. Instead of stopping to help, they run...and leave lots of clues in the process.
At the same time John is in trouble, his father (Murray Hamilton) is also in trouble. It seems his company is in financial trouble and the folks offering to 'help' are mobsters...who likely will destroy his company in the process. He tells the mob to get lost....but what is going to happen when these crooks learn about John and his little 'indiscretion'?
This is a very good episode...well worth seeing and a chance to see Grady play something other than a Mouseketeer or a Douglas from "My Three Sons".
