Ray Whitley inherits the Lazy W Ranch, but the local attorney informs him that the will has one condition: Whitley must not sing or play or even whistle a single note of music for 30 days. Otherwise the property goes to the ranch foreman, Jim Readick. Whitley and his Six Bar Cowboys spend the rest of the film trying to get around the "no music" rule with several vocal and instrumental numbers. Meanwhile, Readick schemes to trap them into violating the terms of the will.
