Plot:
On an island lighthouse, Tom meets his girlfriend, Vi, and refuses to drop his fiancee to marry Vi. She still has a number of letters he wrote her. Vi falls off the lighthouse railing.

Raise your hand if you're sure!
Tom is a bit too slow to save her which happens to end his problem. The next day, he mistakes some seaweed for Vi's body. He spends a lot of time trying to console that Vi's death
isn't his fault, etc.
Tom meets with his intended, Meg.

Shouldn't some giant grasshoppers be climbing that lighthouse behind us?
On the beach, Tom keeps seeing footprints no one else does while spectral music plays. Tom is starting to act awfully strange and even tries to talk Meg into getting enloped a few
days earlier than the their upcoming wedding.
Mrs. Ellis, the blind real estate agent, tells Tom about the haunted island house. Later, spectral Vi calls for Tom. Let the nightmares ensue. Tom sees that the lighthouse is lit. Heading out to it he proclaims he won't be haunted by Vi, etc...
Tom keeps continually seeing a spectral Vi who haunts him. He calms down for Meg. However, he isn't the only one haunted. Meg discoveres her wedding dress was slashed and doused in seaweed.
Tom tells Mrs. Ellis about Vi as the crazy ex-girlfriend stalking him. She heads out to the lighthouse, at the top, she almost falls through the railing and is starting to think there must be some sort of ghost on the island.
Sandy, Meg's little sister (but not in the Little Sister song version) has a big crush on Tom.

Harry Houdini's secret childhood is finally revealed...
This scrufffy guy is looking for Tom. Apparently, he piloted Vi to the island but she never paid him. Tom pays the guy. Lter, the guy learns that Tom is marrying the wealthy
Meg.
At the wedding rehearsal, guy wants more money from Tom or else he mentions about Vi.

Why do you keep thinking a giant superimposed floating head would be chasing you?
Vi is claiming that he belongs to her and accuses that he murdered her. Guy wants Tom to pay him more because he knows Vi came to the island but never left. Tom offers
to meet him at the lighthouse later. Ghostly Vi tells Tom he'll have to get rid of the boat captain. Tom clubs the guy to death. Sandy is hiding in the top of the lighthouse.
Right before the wedding, Sandy keeps from telling Meg about Tom murdering the guy. During the ceremony part of the "speak now or forever hold your peace" the church
doors fly open and the flowers wilt. Tom runs off.
At the lighthouse, Tom tells Vi that is running away from Meg. Sandy followed him. He's worried what she can say after he learns she knows about the dead boat captain.
Meg and her parents head to the lighthouse.
Tom takes Sandy to the top of the lighthouse and is slowly edging her close to the rickety railing. However, Vi scasres him off.
A couple of days later, people find Tom and Vi's bodies in the ocean. Somehow, Vi is wearing the wedding ring Tom lost before the wedding.

Who knew a corpse floating out in the ocean for several days would be so preserved?
