Angel - Old Friends (2006)

Joss Whedon's classic character returns for his next all-new adventure! When a strangely familiar, seemingly vampiric figure is spotted killing victims in Los Angeles, Angel, alone in semi-retired retreat while he figures out what's next for him, is lured back to the city to put a stop to the string of slayings. The case will reunite the vampire that has a soul with old friends and old enemies - but it's impossible to tell which is which!
