- "No one has been hurt and Scott will keep a check on the situation. He'll realise that this is not a job for International Rescue."
— Jeff Tracy
Lady Penelope persuades the overworked Jeff to take a vacation with her, at her Australian sheep farm. Scott takes his place in charge of International Rescue. He is chided by his father for sending the team to a fire at the oil rig Seascape, when their help was not needed - but the situation later worsens, when ignited gas starts pouring through cracks forming in the sea bed around Seascape's foundations...

International Rescue Equipment Used
Non-International Rescue Equipment Used
- Alan pilots Thunderbird 1 in this episode, due to Scott being left in charge of Tracy Island while Jeff was away, the Tracys noting that the decision makes sense as Thunderbirds 1 and 3 are rarely used on the same assignment.
- As Season 2 begins, a number of slight modifications have been made to the character designs, their wardrobes, and even the Thunderbirds themselves.
- The opening shot of Australian outback was previously used for the opening shot of Cry Wolf, another story set in the land down under.
- Parker reveals that there are 200,007 sheep on Lady Penelope's sheep farm.
- The Mobile Control Centre makes its only Season 2 appearance (and last-ever, in the series overall) in this episode. It would later appear again in Thunderbirds Are Go.
- Along with The Mobile Control Centre, this is also the final appearance of Thunderbird 4.
