It stars all the then-surviving original cast (Hank Patterson (Fred) and Barbara Pepper (Doris Ziffel) died in 1975 and 1969 respectively).  The movie starts with the original opening credit sequence from the series, but in a sepiatone color to tell you that it's been a while since the TV show ended.

The Douglas' trusty farmhand Eb (Tom Lester) has married a girl named Flo.
