On their way home from the Malt Shop, the gang encounters "The Ghost of Mr. Hyde", a known jewel thief, sneaking into a spooky house. The house turns out to be the home of Dr. Jekyll, who fears he may be transforming into the Ghost of Mr. Hyde. The gang begins searching the house for clues, pegging the maid as a likely suspect, but are pursued at every turn by the ghost.
A ghastly, green-faced figure scales a downtown highrise building and escapes with a jeweled necklace; fleeing a policeman, he hides in the back of the Mystery Machine, which is parked at the Malt Shop. He springs out at the gang as they are driving through a short cut and disappears into the fog-shrouded marshes. The gang recognize him as the ghost of Mr. Hyde, a creepy jewel thief that has been haunting the city. They track him to a dilapidated old mansion and fall through a trapdoor into a scientist's lab when they try to follow. There they meet Dr. Jekyll, who tells them a wild story about an experiment-gone-wrong that might be changing him into the ghost of Hyde. He gives the gang permission to look around.
Scooby and Shaggy search the attic, where they find trunks of old costumes—and deduce that someone in the house must have been in show business—but are scared off by Helga, the housemaid, before they can dig any deeper. They are then chased from the library by the ghost of Hyde. Meanwhile, Fred has found a partially burned newspaper article describing the exploits of Helga the Great and her human fly act. The fleeing Shaggy and Scooby knock Velma down and the three land with a thump in the laundry room, where they find that someone has hidden away a pair of muddy shoes and Helga's feather duster. That's enough to send the gang to Helga's room, where they find a can of phosphorus paint and some knockout drops hidden under her mattress. They have just decided to confront Helga when Shaggy appears, claiming to have found something interesting in a fruit bowl in the hallway. But he is instantly grabbed by the ghost of Hyde and hustled downstairs into the laboratory.
The ghost is about to turn Shaggy into a frog, but is foiled when Scooby charges to the rescue. He and Shaggy elude Hyde (at one point poling through the marsh on the back of an alligator) and hook up with the others; Shaggy shows them the suction cups that he found in the fruit bowl. Fred, Velma, and Daphne declare that they've solved the mystery, then lay a trap for Hyde: Shaggy and Scooby lure the ghost into rooms where the others, themselves disguised as Hyde-lookalikes, spring out at him. Hyde flees toward the backdoor, falls through the trapdoor, and is bustled up in a mattress by Shaggy and Scooby. He is unmasked as Dr. Jekyll, who, after his experiments failed, had decided to turn to a life of crime. When he saw that the kids were onto him, he then planted clues about the house to frame Helga.

- "The Early Late Show" may be a play on The Late Late Show.
- This is one of the few Scooby-Doo, Where Are You! episodes that seems to deliberately try to deceive the audience into thinking that someone innocent is the villain, and also one of the first examples of the villain trying to frame another named character.

Animation mistakes and/or technical glitches
- After he enters the basement, Dr.Jekyll's shadow vanishes. Later, Mr.Hyde's does, too.
- While watching Shaggy and Scooby slide down the bannister, Fred turns his head all the way around. Ouch!
- The mud on Jekyll's shoes wasn't there a moment before.
- Shaggy runs right through the wall, leaving a Shaggy-shaped hole...complete with floating pieces of wood to delineate the negative space in the crook of Shaggy's arms!
- The picture on the wall is just a solid blue. Modern art?
- When Scooby was climbing the wall at the end of the episode, he had suction cups on all four of his paws and one on his tail, but when he was on the ceiling, his front paws had no suction cups on them with no time for him to take it off.
- Shaggy has no ear near the end of the episode.
- Velma in the Hyde costume is considerably shorter than normal.
Inconsistencies/continuity errors and/or goofs/oddities
- Dr Jekyll managed to plant all of the clues extremely quickly and yet methodically- unless he was prepared beforehand that someone might follow him, which is not what the Gang believed, this is somewhat miraculous.
- When Shaggy and Scooby claim that "Dr Jekyll must have changed again,", Velma claims this is impossible as she, Fred and Daphne just saw him reading in his study. At this point the audience is being led to believe Helga is the Ghost of Mr Hyde; but after it transpires that Jekyll is indeed the ghost, it means that Jekyll must indeed have moved impossibly quickly.
- It was never really explained why Dr. Jekyll was so intent on getting the suction cups back; certainly he had extras and with all the false clues he planted they could have been dismissed as an anomaly. (although his determination to retrieve them was a big clue to their importance).
