Tom and Anna Wright, a young couple from America, find themselves in deep financial trouble while refurbishing Anna’s ancestral home in London. As their dreams of owning a house and starting a family begin to crumble, they stumble upon a grim discovery: the tenant living in the apartment below has passed away, leaving behind a hidden fortune of $400,000. Initially reluctant, Tom and Anna devise a straightforward plan: discreetly take the money and use just enough to clear their debts. However, as they begin to spend the cash and struggle to rein in their expenses, they unwittingly attract the attention of a dangerous foe—the original thief of the money. This sets off a chain of unfortunate events, where good people find themselves caught in a perilous situation.
