CATnip plot
The Betancourt family moves from New York City to San Pedro. They want a better life and hope to make a fresh start. The move is immediately disappointing, as their new neighbors don't welcome them with open arms. On Christmas Eve, everyone is forced indoors due to a dangerous fog. However, this turns out not to be the biggest problem: a horde of bloodthirsty cats terrorizes the building. The Betancourts and the other residents must work together to survive.
