BloodRayne II: Deliverance

Rayne, a half-human, half-vampire warrior, travels into America’s 1880s Wild West, where a new threat is spreading across the frontier. Billy the Kid has become a vampire, and he rides with a posse of vampire cowboys. To stop them, Rayne must face the dangers of the lawless West and confront an undead outlaw whose gang brings bloodshed wherever it goes.
