Dad Rudd (played by Bert Bailey) identifies the need to increase the capacity of the dam, which would benefit the local farmers. He is opposed by Henry Webster (played by Frank Harvey). After the death of the local member of Parliament, Webster states for election in his place. Rudd realizes that if Webster wins the seat, his ideas for the dam will not go ahead, so he stands for the seat as well. On the day of the election, the dam breaks, trapping workers. The Rudd family and Webster's son Jim (played by Grant Taylor) join forces to save the workers. Dad Rudd wins the elected.
