The innovative series of gay-centered shorts continues with this fifth installment, featuring the films “Dare,” where two high-school boys share a mind-blowing first encounter; “Fishbelly White,” a rites-of-passage drama that takes a boy’s circus-geek trick to a tragic extreme; “Late Summer,” which chronicles a young man’s first revelation as an aspiring photographer; and “Time Off,” the story of a soldier whose abusive commanding officer has a secret.
