Follow-up to 1956's "Rock, Pretty Baby" has teenage guitarist John Saxon and his rock 'n roll combo getting a month-long summer gig at a co-ed camp in Lake Tahoe; he has reluctant eyes for the wealthy lass whose family owns a house nearby ("a female octopus!"), but a visit from his steady girlfriend--not to mention the burden of babysitting his younger brother and sister--may scuttle any hopes for a summer romance. Muscular Saxon and shapely, cunning Jill St. John (in her film debut) both look good in their swimsuits, but this flimsy second-biller from Universal is strictly for sub-teens.
