In Wellington, New Zealand, a documentary crew gains the trust of four vampire housemates and captures their unconventional lives with the agreement that the crew will be granted protection from their subjects' vampiric impulses. The film opens with the vampires trying to cope with the mundane aspects of modern life, such as night-time flat chores, fitting in with society, and dealing with house meetings. Viago, an 18th-century dandy, struggles with lost love; Vladislav, known as Vlad the Poker, grapples with a faded reputation; Deacon is the youngest and most rebellious of the group; and Petyr, an 8000-year-old vampire, lurks in the basement, foregoing social interaction with the rest.

Tensions among the flatmates escalate when they are joined by Nick, a recently turned vampire who struggles to accept his new lifestyle. Nick's induction brings modern influences into the group, along with his human friend Stu, whom the current members grow fond of. The vampires attempt to educate Nick on the ins and outs of their immortality, with varying degrees of success. Meanwhile, they contend with the nuances of contemporary vampiric existence, such as finding sustainable sources of blood, dealing with werewolves, and maintaining their masquerade. The situation becomes complicated as Nick's transformation attracts the attention of a curious vampire hunter, setting off a series of events that challenge the coexistence among the group.
