A deadly, highly-contagious infection laid waste to humanity 25 years ago. Joshua and Penelope are some of only a handful of survivors who are fighting daily for their lives with the remnants of the infected who turned into mindless, flesh-eating, zombie-like creatures. Despite their predicament, Joshua and Penelope feel strongly for each other and are determined to not only survive, but bring a baby into this bleak post-apocalyptic world, but Penelope keeps having miscarriages. The two struggle to make a meagre living by foraging for scraps of food amongst the ruins of what once were towns and cities, occasionally stumbling upon some of the infected.

Then, one day they come across a woman called Abira, who claims that she could lead them to a sanctuary with a large group of uninfected people, that would offer them a more safe place to live in. Initially suspicious, Joshua and Penelope eventually admit Abira to their small group, only to see the attacks of the infected increasing exponentially. Pressed, Abira reveals that she was once bitten by one of the infected, but, miraculously, survived. As an unfortunate side-effect of this encounter, the infected can always somehow ‘sniff her out’ so that wherever she is, she pulls them to her, and anybody in her group, as a magnet. Though the infected do not harm her, anybody else who over the years accepted her company, has paid dearly - as soon Joshua and Penelope learn to their detriment.

Chrysalis, despite its low budget, presents some good acting and a few frights along with the interesting premise on which it fails to capitalise. If you are looking for a good post-apocalyptic horror film, watch Danny Boyle’s 28 Days Later instead.
