13 year old Jacob is devastated when his mum tells him that, due to money worries, they are going to have to move out of London and leave his beloved Grandpa behind. Jacob's grandpa, Kwesi, may be dealing with the effects of dementia but he still regales Jacob with stories of his past as a young man in 90's Hackney.

Sure that finding the diamonds will solve all his problems, Jacob begins a desperate search. But he doesn't find the diamonds - he finds a time machine! Along with his friends, Liam, Aisha and Snacks - Jacob travels back to 1991 to find out once and for all what happened to the diamonds...
