About the title
An unknown epidemic has wiped out humanity — the disease spreads through a bite and turns its victim into a bloodthirsty zombie within 48 hours. The family of Andy, his wife Kay, and their one-year-old daughter Rosie travel along a river, where there's less chance of running into the infected. Searching for supplies, they climb aboard a half-sunken boat, but the outing doesn't end well. Now the clock is ticking, and in that time little Rosie must find a new home.
