Day the World Ended (1955)

In a post-Apocalyptic world after an atomic war seven disparate people find themselves in a protected valley in the home of a survivalist and his beautiful daughter.

Runaway Daughters (1956)

Three teenagers with troubled families are unable to adjust at home and in high-school. Tempted with an easy, carefree life they soon pass from misdemeanors into serious crime - and will suffer for it. Sometimes, repentance comes too late.

Despite presenting a large and lively ensemble the tale itself is lame and its moralizing outmoded. 

Maltin*1/2: "Dull, dated, and overlong, this teen exploitation fare boasts a surprisingly geriatric cast."
