A woman, Sheila Case, is jogging when she glimpses the apparition of a ship in the harbor. Later, while she showers, a figure appears, and the woman dies of drowning.
Dean confronts Sam about having killed the crossroads demon, a fact he deduced due to a bullet being missing from the Colt. He is angry that Sam put himself in danger. Sam is unapologetic.
The boys visit Gertrude Case, Sheila’s aunt, inquiring about the circumstances of her death. They are surprised when Gert, who is obviously attracted to Sam, suggests Sheila may have seen a ghost ship, and asks if they are working the case with “Alex.”
Outside, Dean panics when the Impala is missing, until Bela appears and admits she had it towed. She tells them she scams old women by selling them fake charms and doing seances for them. She says that she, calling herself "Alex," had convinced Gert that she had solved her niece’s murder, but since the boys showed up Gert is withholding her payment.
That night, a man dies, again by drowning at home. Sam and Dean speak to his brother, Peter, and find out that they both saw a Ghost Ship while night diving. The boys try to protect Peter, but that night he, too, is visited by the Sailor’s Ghost and drowned.
Bela turns up at the house where the Winchesters are squatting, with information – the ghost ship is the Espírito Santo, and it is a death omen. The ghost is that of a sailor who was hung for treason. His hand was removed after death to make a Hand of Glory, and Bela suggests they need to retrieve and salt and burn it in order to vanquish the spirit.
Gert obtains invitations for Sam, Dean, and Bela to a function at the Maritime Museum where the Hand of Glory is kept. While Sam keeps Gert, and her wandering hands, busy, Dean and Bela steal the Hand of Glory.
Bela tricks Dean and leaves with the object, which she sells to a client – her goal all along. But then she, too, sees the Ghost Ship.
Meanwhile, Sam and Dean have deduced that what links all the deaths is that the victims were involved in the death of a family member. Bela turns to the boys for help; although she admits to having been involved in someone’s death, she won’t elaborate.
At the sailor’s grave, Sam summons the ghost of the ship’s captain who had the sailor killed – his brother. Their spirits 'merge' and disappear, and Bela is saved. She shows her thanks by giving the boys $10,000.
Dean is keen to head to Atlantic City for some fun. He apologizes to Sam for the pain his bargain with the Crossroads Demon is causing, but Sam angrily counters that he doesn’t want Dean to worry about him, he wants Dean to care about himself.
You could have gotten yourself killed!
Sam: I didn't.
Dean: And you shot her.
She was a smartass!
What a crazy old broad.
Sam: Why? Because she believes in ghosts?
Dean: Look at you, sticking up for your girlfriend. You cougar hound.
Sam: Bite me.
Hey, not if she bites you first. So, who's this Alex? We got another player in town?
How do you sleep at night?
Bela: On silk sheets, rolling naked in money. Really, Sam. I'd expect the attitude from him, but you?
Sam: You shot me!
I barely grazed you.
Dean: Can I shoot her?
Sam: Not in public.
Hey, Bela, how'd you get like this, huh? What, did Daddy not give you enough hugs or something?
Bela: I don't know. Your daddy give you enough? Don't you dare look down your nose at me. You're not better than I am.
Dean: We help people.
Come on. You do this out of vengeance and obsession. You're a stone's throw from being a serial killer. Whereas I, on the other hand, I get paid to do a job and I do it. So, you tell me – which is healthier?
Dean: A Hand of Glory? I think I got one of those at the end of my Thai massage last week.
Bela: You know, when this is over, we should really have angry sex.
Dean: ...Don't objectify me... Let’s go.
Bela: Please. I need your help.
Dean: Our help? Now how could a couple of serial killers possibly help you?
I've come to settle affairs. Giving the spirit what he really wanted, his own brother – very clever, Sam. So here. It's ten thousand – that should cover it. I don't like being in anyone’s debt.
Dean: So ponying up ten grand is easier for you than a simple thank you? You're so damaged.
Takes one to know one. Goodbye lads.
I don't want an apology from you! And by the way, I'm a big boy now, I can take care of myself.
Dean: Oh, well, excuse me.
Sam: So would you please quit worrying about me? I mean that's the whole problem in the first place. I don't want you to worry about me, Dean, I want you to worry about you! I want you to give a crap that you’re dying! So, that's it? Nothing else to say for you?
I think maybe I'll play craps.
The title of the episode comes from an old piece of weather lore
: “Red sky at night, sailor’s delight. Red sky at morning, sailor take warning.” Red sky at morning is said to signal rain.
...Happy Purim? Dude, I don't know. I have no idea what you're talking about—
- Purim is a Jewish holiday which commemorates when the Jewish people living in Persia were saved from extermination. Purim occurs during February/March.
The sailor's body was cremated, but not before they cut off his hand to make a Hand of Glory.
- A Hand of Glory appears in the Harry Potter books, as well as the Sandman comic by Neil Gaiman and his novel "Neverwhere". One also appeared in the TV series The Dresden Files in the episode "Walls."
This'll get their tongues wagging, eh, my Adonis?
- Adonis is a figure from Greek, and earlier, mythology. The term is used to refer to an attractive young man.
Oh, look at you. Searching for a witty rejoinder.
Dean: Screw you.
Bela: Very Oscar Wilde.
- Oscar Wilde was a famous 19th century writer, renowned for his witticisms. He spent two years doing hard labor in prison because of his homosexuality. Notable is also the "new cussing" that's going on in this episode. Twice the term "screw you," a milder form of "fuck you," is uttered; and several times Sam or Dean use the word "crap." (New regulations for cussing on prime-time TV were released in June of 2007.)(Source)
You got it, right? Tell me I didn't get groped all night by Mrs. Havisham for nothing.
- Miss Havisham is a character from Dicken's Great Expectations, an aged spinster who takes an interest in Pip, the main character.
So they were brothers. Very Cain and Abel. So now our spirit, he's going after a very specific kind of target – people who've spilled their own family’s blood. See first there was Sheila who killed her cousin in the car accident, and the Warren brothers, who murdered their father for the inheritance. And now you.
- Cain and Abel were the sons of Adam and Eve, and Cain, in killing Abel, commits the first murder.
