Publisher's summary
The TARDIS lands in Berlin in the 1930s, where Hitler and his National Socialist party are in the ascendant.

Some of the greatest scientific minds are gathering here: Einstein, Heisenberg, Planck, Schrödinger, Wigner. The people who will build the future of planet Earth.

But the Doctor and Susan have brought something with them. Something apparently harmless, something quite common. Yet something that could threaten the course of history...

Wedding Gold (1)
In the TARDIS, Susan is writing a letter to Barbara. She explains this is a letter to be opened only if she died or has left the TARDIS. In the first case, she asks Ian and Barbara to look after her grandfather; in the second one, she asks them to ensure he doesn't go back in time to change that. She worries, she said, about what the Doctor would do without her. She says that, even though he told Barbara they can't change history, this is not exactly true: every action has consequences, every action, though minimal, can change the present and the future of everyone.
