chunk: Ben and Barbra are unaware that the farmhouse has a cellar, housing an angry married couple Harry (Karl Hardman) and Helen Cooper (Marilyn Eastman), along with their daughter Karen (Kyra Schon). They sought refuge after a group of the same monsters overturned their car. Tom (Keith Wayne) and Judy (Judith Ridley), a teenage couple, arrived after hearing an emergency broadcast about a series of brutal murders. Karen has fallen seriously ill after being bitten by one of the monsters. They ventured upstairs when Ben turns on a radio, while Barbra awakens from her stupor. Harry demands that everyone hide in the cellar, but Ben deems it a "deathtrap" and continues upstairs, to barricade the house with Tom's help.
