Plot

A scientist is using Microbes in experiments but dies before the work is finished. An aging actress injects herself the serum and the bacterium transforms her into a hideous bug alien resulting in an attrition problem among her detractors.

Microbes are brought back to earth via a space probe from Venus. A scientist is using them in experiments on aging, but dies before the work is finished. His assistant approaches an aging actress who is being passed by for the lead roles, and she injects the serum hoping to become young again. When the actress is still passed up for the plum roles, the alien bacterium transforms her into a hideous bug-like alien resulting in a predictable attrition problem amongst her detractors.—Ed Sutton <esutton@mindspring.com>

A scientist is locked in the laboratory by his assistant Evelyn Avery and a mutating creature attacks him. He turns into a monster and then he attacks a young man outside the building, but is killed by his girlfriend that crashes her car on him. Meanwhile, the aging actress Lynn Roman, who is a former famous star, is fighting for a lead role in a movie directed by Mark Randall. However, Mark wants a younger actress between twenty and twenty-five years old for the role. Out of the blue, Evelyn meets Lynn and tells that her secretary Elaine allowed her to meet Lynn to show an injection with a serum developed by Dr. Emil Zeitman that would make her younger again. Lynn uses the experiment and turns into a monster, becoming a threat to her friends.—Claudio Carvalho, Rio de Janeiro, Brazil
