The daily lives of a typical Brazilian middle-class family, that are always very close and tries, in their way, to survive the financial and relationship difficulties.

With the help from his little guardian angel, Xuxinha, a 7-year old boy called Guto faces the terrible garbage eating monsters from the planet XYZ in the first-ever animated Xuxa film.

位于南里奥格兰德州内陆的一个小村庄，居民们已无法忍受下水道污水的恶臭。村民玛丽娜（费尔南达·托雷斯饰）带领村委会，向市政府申请8000雷亚尔用于改造污水池，但政府表示没有此类卫生项目的预算，却有10000雷亚尔可用于一部电影的制作。
玛丽娜和她的丈夫华金（瓦格纳·莫拉饰）决定以拍摄电影为原由申请预算，再将预算的一部分用于污水池的改造，剩余的部分则用于拍摄一部讲述怪物在污水处理厂制造恐怖事件的低成本电影。
