Solomon is a large black cat. He lives in a second floor London apartment with his owners Rachel and Tom. Unable to go out on his own he spends hours each day looking out from his sunny seat on the windowsill, dreaming of running through the grass in the park across the road. Desperate he plans an escape to realise his dreams. Little does he know that this is the start of a much bigger adventure involving trees, queens, underground trains and feral cats not to mention a fight for his life.
