Roswell - Season 3 Episode 17

The scientists studying the crashed UFO discover a baby inside, but to protect the baby, the other passenger kills them all and takes the baby on the run. Just as their parents are confronting them with a video of Isabel using her alien powers, Max hears an intruder and goes to the kitchen to find Tess holding the baby. There is little time to explain to their parents as they need to get out before the Air Force comes into the house searching for the alien. So now the group of friends must decide what to do with Tess as several of them want her to pay for Alex's death, but others aren't comfortable killing her. They must also trust that Isabel and Max's parents will not betray them to the government agents in pursuit.
