My Three Sons

The Heartbeat (8x11)

Data di messa in onda: Nov 18, 1967

One stormy night while Steve is in San Francisco, Katie is alone in the Douglas house while the rest of the family is attending a ballgame. Her tenseness builds as late in the night she hears a scary rythmic noise, and hysterically calls Steve to report that the family has not yet returned and that she hears a loud thumping sound.
