Lou and Peter’s new home returns into a renovation nightmare which results in a tragic and potentially fatal situation. Jack’s European vacation did not work out as well as he leads Lisa to believe and a newcomer, an 11-year-old runaway by the name of Georgie, becomes a new fixture at the Heartland Ranch.
