Ep 2. Planet of Giants: Dangerous Journey

The second episode of the second season of Classic Doctor Who, entitled "Planet of Giants: Dangerous Journey," follows the adventures of the Doctor and his companions Ian, Barbara, and Susan as they shrink down to a minuscule size and find themselves in a dangerous and unfamiliar world.

The episode opens with the TARDIS landing in what the Doctor thinks is a normal-sized insecticide laboratory. Unknown to him, however, is that a malfunction in the TARDIS' size control circuit has caused the travelers to shrink down to the size of insects. They quickly realize their situation as they find themselves struggling to climb over everyday objects and navigating through an environment completely unfamiliar to them.

The initial danger that they face is from the unsuspecting laboratory staff who are performing experiments, and the crew must quickly use their intelligence and resourcefulness to avoid being spotted. They manage to escape the laboratory and make their way outside, where they are faced with a world that is terrifyingly immense to them. A garden becomes a jungle, a cat is a ferocious predator, and even a simple drop of water becomes an insurmountable obstacle.

As they traverse the garden, the crew discovers that something sinister is afoot. The insecticide the lab is creating is far deadlier than anyone could have imagined and could potentially wipe out all insect life on Earth. The Doctor, Ian, Barbara, and Susan must find a way to alert the authorities, but as they soon learn, even the smallest actions can have unintended and drastic consequences. The group's size makes even the simplest of tasks an immense challenge, and one wrong move could cause catastrophic events to occur.

Throughout the episode, the group must use their ingenuity to escape deadly traps, evade their larger-than-life predators, and find a way to restore themselves to their normal size. They are put to the test at every turn, as they navigate through a world that is both familiar and completely foreign, all while trying to prevent global disaster.

Overall, "Planet of Giants: Dangerous Journey" is a thrilling and heart-pounding episode in the Classic Doctor Who series. It showcases the intelligence and bravery of the Doctor and his companions as they face impossible odds and navigate through a world that is completely out of their control. The episode is filled with suspense, action, and adventure, and is a must-see for fans of the series.
