Nella tranquilla e ridente cittadina di Haplin, definita per l'appunto Happy Town, si trasferisce una nuova ragazza Henley con l'intenzione di aprire un negozio di candele con l'eredità avuta dalla morte della madre. Nella cittadina non avvengono crimini efferati da 5 anni, dall'ultima volta che Magic Man ha fatto scomparire la piccola Haplin di 8 anni, figlia del proprietario della grande fabbrica di pane sopra la collina. Viene però ritrovato in un capanno sul lago ancora ghiacciato, il corpo del guardone della città, il signor F. con un buco in fronte, opera di un misterioso assassino.

Cominciano le indagini che portano lo sceriffo Conroy di Haplin e suo figlio a recarsi dai fratelli Stivaletto. Lo sceriffo mentre si trova con il figlio Tommy comincia a parlare di una misteriosa Chloe ma alla domanda del figlio su chi sia questa donna, per più volte, lo sceriffo non saprà rispondere, sembrando anche in trance.
