Sam and Dean investigate a murder at a museum, uncovering that a ghost from a merchant ship, which sank in 1723, could be behind the crime. They discover that "The Star" was the ship that Crowley’s son, Gavin McLeod, was meant to be on. To locate Gavin, they seek assistance from Rowena. Meanwhile, Kelly Kline, who is still pregnant with Lucifer's child, finds sanctuary with a demon after an angel tries to assassinate her.
