Meet next-door neighbours, Beth Hunter and Hal Moon. Beth's imagination's always getting her into trouble and Hal's practical jokes always backfire . . . But when mystery stares them in the face, Hunter and Moon are on the case!
Beth spots strange lights from her window late at night - glowing green in the distance, then disappearing. She's convinced there's been an alien landing but Hal saw them too and he's not so sure. Until a midnight encounter leaves them both thinking . . .
