Sapphire and Steel

A wealthy business man holds a 1930s-themed party for his guests, but all is not what it seems. Sapphire and Steel invite themselves to investigate.

A game of hide-and-seek is played before dinner, but one of the guests will be murdered.

The party guests begin to realize that they are trapped, but their memories are beginning to fail and confusion is taking over.

Two of the party guests are dead. Who will be next? This is no traditional murder mystery, and Sapphire and Steel cannot agree on who would have a motive to commit this crime.

Sapphire and Steel realize that things must play out exactly as they would have in 1930 or the human race is doomed, but something is trying to interfere with time.

Sapphire and Steel allow things to unfolding order to find the point in time when things will be changed. Only then can they ensure that time is put back on track and reset the correct future.
