Parasites

Mina becomes fond of John, a man she meets on a river barge, and agrees to meet him later, to serve him lunch in exchange for Wellington boots for the community. However, when the boat returns, two other men have taken residence, and John is nowhere to be found, though one of the men is wearing John's hat. The pair are brought to Whitecross but appear quite aggressive. Pet recognizes one of them as a convicted criminal, and when Mina finds John's murdered corpse and confronts the pair, they take the children hostage. In an attempt to reason with them, Lewis goes to talk to them but is shot dead. Greg and Charles meet the men's demands and let them go, and the pair escape on the boat. However, they begin to suffer the effects of the wood alcohol they've been drinking and die.
