Part 4 of 5. Aunt Clarice and Mama Lilith arrive in time to dish out mischievous tricks and wicked treats as Sicko and the gang celebrate their first Halloween outing in the City of Sin. It's a tribute to the Silent Screams of yesteryear, featuring Sicko's twisted and tasteless alteration of what horror fans consider the ultimate film classic of German Expressionism... The Cabinet of Dr. Caligari (1920). Shot on location throughout Las Vegas... this one's epic!
