Life After Mutation is a zombie movie project.

Two freshly hired lab technicians for a pharmaceutical company decide in a late night shift to manufacture some illicit recreational drugs under-the-table for a coming party. In the process they mix up a ingredient and mistakenly use one the company's experimental mutagen.

Once at the party everything seems to go well, the drug give their intended recreational effects and everybody is happy. But later on the mutagen seem to take over and slowly but surely a mutation is taken place in each person who ingested the drug.
The process is slow and gradual, not hours but days go by before they reach their final state of mutation: total zombification!
