Ep 30. Lord Parker's 'Oliday

In Thunderbirds season 1 episode 30 titled "Lord Parker's 'Oliday," the Tracy family receives a distress call from The Hood, who has trapped Lady Penelope and her chauffeur, Parker, on a tropical island. Parker, who is on holiday, is more concerned about his tan than his rescue, while Lady Penelope remains calm.

Scott and Virgil set off in Thunderbirds 1 and 2 to save Lady Penelope and Parker, but they are not alone. The Hood sets a trap using a fake distress signal, causing Thunderbirds 1 and 2 to collide and crash onto the island. Lady Penelope and Parker, who are in a nearby cave, hear the crash and go to investigate, discovering the wreckage and realizing their rescuers are in trouble.

Meanwhile, The Hood seizes the opportunity to strike and tries to steal Thunderbirds 1 and 2. He takes control of Thunderbird 2 and attempts to use it to break Thunderbird 1 out of the cave where it has become trapped. Lady Penelope and Parker manage to jump aboard Thunderbird 2 and disable The Hood's control, freeing Thunderbird 1 in the process.

In their triumph, Lady Penelope and Parker, who is now more enthusiastic about the rescue mission than his holiday, join the rescue effort and ultimately help to save the day.

The episode ends with the Tracy family and their allies returning to their headquarters, where they reflect on the recent events and enjoy a moment of rest before the next mission.
