Hoping to ape the success of Sol Lesser's Bobby Breen musicals, Republic Pictures fashioned Dangerous Holiday as a movie vehicle for pint-sized violin prodigy Ra Hould. The star is appropriately cast as preteen violin virtuoso Ronnie Campbell who is so coddled and protected by his family and handlers that he never has a chance to be a "real boy." When he can stand no more, Ronnie runs away from home, whereupon everyone -- including the cops -- assume that the boy has been kidnapped. Meanwhile, Ronnie, together with his new street-urchin friends, stumbles upon a gangster hideaway. In time-honored "Our Gang" fashion, the kids outwit the crooks, whereupon Ronnie's mom and dad promise to give him more freedom of movement in the future. Billed second after Ra Hould is matronly actress Hedda Hopper, who within a year would become one of Hollywood's most powerful (and feared) gossip columnists.
