An assortment of relatives come to visit John Hamilton at his isolated house on an island, connected to the mainland by a causeway. The local legend is that a hundred years earlier a pirate ship had sunk there -- the remains can still be seen offshore -- and one night a year, this night, the ghost of the pirate captain can be seen from the shore. Then one of the houseguests is killed and the movie shifts gears.
It starts off as a lighthearted old-dark-house/mystery/comedy from Republic under the direction of Howard Bretherton, the studio's reliable jack-of-all-genres, and the B-list acting talent available for the studio's non-western programmers are up making the most of their roles and the spooky camerawork of Bud Thackery. It maintains its interest right to the end, although the mystery aspect of the movie is lazily handled; still, that fits right in with its multi-genre script, and more in keeping with its sense of being a mood piece, rather than a serious effort.
