Ep 1. Adventure One - Part 1: Escape through a Crack in Time

Sapphire and Steel is a British sci-fi television series that aired from 1979 to 1982. The first episode of the first season is called Adventure One - Part 1: Escape through a Crack in Time.

The show begins with a group of people being transported through time and space against their will. They find themselves in a strange mansion where time has ceased to exist. After wandering around, they realize that the mansion is actually a pocket of time that has been cut off from the rest of the world.

Sapphire and Steel arrive on the scene and introduce themselves as "elements," beings who have been assigned to clean up events that threaten the fabric of time and space. They explain to the group that they are trapped in the house and that they cannot leave because time is not flowing as it should be.

As they explore the house, Sapphire and Steel discover that the timeline has been disrupted by an entity that has come from the future. The entity has created a "crack in time" that is allowing it to enter and leave different time periods at will.

Sapphire and Steel are able to enter the crack and explore the future, where they find the source of the disruption. They encounter a girl who claims to be from the future and who possesses advanced scientific knowledge. Sapphire is able to communicate with her telepathically and learns that the girl is being controlled by a malevolent force.

Meanwhile, the rest of the group in the mansion begin to experience strange phenomena. They are attacked by unseen forces and some of their possessions disappear. They realize that they are being targeted by the entity that is causing the disruption in time.

Sapphire and Steel return from the future and explain to the group that the entity must be stopped. They devise a plan to enter the crack in time and confront the entity directly. They do so and engage in a fierce battle, using their unique abilities to try to gain the upper hand.

The episode ends with Sapphire and Steel seemingly victorious, but with a sense of foreboding that there may be more challenges ahead.

Adventure One - Part 1: Escape through a Crack in Time sets the stage for the rest of the series, establishing the characters of Sapphire and Steel and their role as "elements" tasked with protecting the fabric of time and space. The episode introduces several intriguing concepts, such as the pocket of time and the crack in time, and sets up the mystery of the malevolent entity that is causing disruptions. Overall, it is a gripping and engrossing start to the series that leaves audiences eager to see what comes next.
