While at the hospital looking for some hard-to-find medicine, Harrison comes across gruesome evidence that the aliens are experimenting on humans. Meanwhile, Malzor and Mana try to find a way to increase their Morthren numbers here on Earth.

When an attempt to hack into the humans' computers goes awry, a Morthren technician (Kemo) is scarred both physically and mentally by the experience. Facing execution, he flees and takes over the identity of the human hacker he killed.

While the aliens try to recover a malfunctioning surveillance device, the team plots a surprise birthday party for Debi.

In desperate straits, the aliens gain a piece of valuable information: the identities of Harrison, Suzanne, and Kincaid. Soon the team has been accused of bank robbery and murder, and Malzor has taken over the police investigation.
