Rodeo stock owner Jame Rodriguez has been framed for supposedly dealing in marijuana, and he is determined to find out the truth. His young son, Daniel, proves most helpful and Jame enlists his wife, Darcy, and good buddies Tony and Bo. The "grassbusters" group tries various schemed to flush out the nefarious dope dealer who framed Jame, and their capers take them around the county, across the Mexican border and back again to trap the culprit and clear Jame's name.
