Os Assassinos do Raio Azul (1978)

At a party, someone goes insane and murders three women. Falsely accused of the brutal killings, Jerry is on the run. More bizarre homicides continue with alarming frequency all over town. Trying to clear his name, Jerry discovers the shocking truth...people are losing their hair and turning into violent psychopaths and the connection may be some LSD all the murderers took a decade before.
