The Family Tree
John and Olivia Walton are preparing to celebrate their 25th anniversary, with each one keeping secrets regarding their present to each other. The children are also busy preparing a surprise family party for them, and Jim Bob is making his own surprise which ends up blowing the fuses throughout the entire house. Olivia gets a telephone line put on for John, and John builds a gazebo for Olivia on the top of the mountain.
The two head off to have their photo taken leaving the children time to get their party ready. However the surprise is on them because the two do not return home. Grandpa, however guesses that John's secret has something to do with the mountain and so they pack up the party and take it up to the mountain where they find John and Olivia dancing in the gazebo.
While all this is going on, Mary Ellen and Curt are having problems adjusting to being apart. They both feel that they have had very little time to learn about each other and have each been tempted to stray to other people. Curt arrives home unexpectedly just in time for the party, and to allow them to spend some time together.
