Cora and Jacob live in London's vast metropolis; he at one end of the Central Line, she at the other.

When a chance encounter on the underground brings them together, it seems they're destined to fall in love.
But life has a catastrophic way of throwing up obstacles that could see both their lives unravel. And as events in their pasts begin to pull them apart, Cora and Jacob begin to wonder:
Are they meant to be together, or were they never meant to meet?
