Henry Pym develops a new plant growth serum that rapidly increases vegetation to enormous proportions. Unfortunately for Pym his invention is too effective and the plant he tested the formula on soon starts growing larger than the building itself. Pym realises with growth this rapid the plant will soon overrun the city and there’s no time to create an antidote. Thus the scientist decides to shrink down to Ant Man and destroy the plants root.
