Centered around a deep-space hospital, the Doctor and his companion, Leela, find themselves caught midst a sudden and catastrophic epidemic. In a twist of events, the malevolent force behind the epidemic is an obscure, sentient virus that seeks to consume and conquer everything in its path. The invisible enemy as referred to in the title, is a testament to the ingenious, unseen forces that often pose the most lethal threats.

The narrative perfectly encapsulates the audacious creativity that Doctor Who is renowned for, pushing the envelope of conventional storytelling by blending thrilling twists and turns with intellectual science fiction.

Tom Baker's portrayal of the fourth incarnation of the Doctor stands as the centerpiece of the episode. His eccentric demeanor and sharp wit bring an enigmatic charm that captivates audiences, while his compassionate and courageous spirit embody the quintessential hero within an apocalyptic scenario—traits that have become synonymous with the character of the Doctor in the series. Accompanied by Leela, played with great charisma by Louise Jameson, the duo confront their invisible enemy while battling their visceral fears, showcasing the human essence at the core of the series.

While the special effects of the 1970s might seem rudimentary compared to the standards of today, they serve an integral part in shaping the aesthetic mood of the episode, giving it a retro appeal. The set design, ranging from the futuristic hospital to outer space, forms the perfect backdrop for the unfolding drama, enhancing the storytelling with a visual representation of the sci-fi theme.

As with any Doctor Who episode, the Invisible Enemy is wrapped in moral and philosophical dilemmas, resonating with universal themes of survival, courage, and the human spirit against adversity. The narrative shows how sometimes the most formidable enemy can take an invisible form, which challenges the characters to face their fears and surpass their limitations.

Just as pertinent, the episode explores the idea of the ethical implications of scientific progress, especially in the field of human health and well-being. It deals subtly with the constant interplay between advances in science, arguably necessary for the survival of the species, and the constant risk of these developments backfiring.

Invisible Enemy is a classic Doctor Who episode, where the science fiction elements mingle beautifully with deep philosophical introspection, adding layers of complexity and intrigue to the story. It remains true to the anthological format of the series, where each episode stands as an independent narrative, yet subtly contributes to the overarching continuity of the show. This makes the episode accessible for both dedicated fans and new viewers of Doctor Who.

In conclusion, Doctor Who: Invisible Enemy is a gripping emblem of the paradoxical 1970s era of science fiction television, an innovative blend of suspense, humor, and profound contemplation. The episode successfully captures the tonal essence of the Doctor Who series, which is to entertain, inspire, and challenge perspectives with thought-provoking scenarios.
