On this page of the Cyberpunk 2077 game guide you will find a detailed description of the Double Life job.
V and Judy managed to find and save Evelyn Parker. The woman was kept by the Reapers, who set up a studio for recording black braindances (XBD) in a nearby old power plant.
Rewards for the task: 1 Attribute point, 1 Perk point, Street Cred points.
Talk to Judy
Talk to Johhny, and then go inside the building to talk to Judy. There is no contact with Evelyn, and Judy found two special recordings on her behavioral chip that she wants to show you. When you are ready, go to Judy's studio to analyze the braindances.
Look for clues in the recording
First, watch the whole recording to get a little bit closer to the subject, then go to the edit mode to find the necessary clues.
Turn on the visual layer and move the recording to 00:1 second. Scan the Voodoo Boys hologram (veve symbols) above the altar.
Stay in the visual layer and do not move the recording. Scan the anonymous netrunner - you cannot recognize her face.
Stay in the visual layer and move the recording to about 00:30 seconds. When Evelyn looks down, scan the flyers scattered on the floor. You can now leave the braindance and talk to Judy. It seems that Evelyn wasn't honest with you - she got an order from Voodoo Boys to record braindance and instead she organized the theft of a biochip from Konpeki Plaza. A gang of netrunners took revenge on her and led to an incident in the Clouds.
Watch the braindance
Judy will show you another braindance - watch it to the end. Evelyn eavesdrops on someone on the phone in an unknown language. V suggests that it could be Creole and Judy will start looking for an auto-translator.
Reset the recording, switch to the audio layer, scan the phone and listen to the whole conversation again. You can now leave the braindance.
Judy wonders what Johnny Silverhand has to do with it. Atthis point you can hide all information from her or explain to Judy what was on the biochip you stole from Konpeki Plaza.
Your answer may affect how your further conversations with Judy will proceed when completing the side jobs, so think about whether you want to lie to her now.
Talk to Johnny and try to figure out what these people might want from Alt. Johnny unfortunately does not know the answer to this question, but he suggests finding a netrunner and talking to her about the biochip. Go to the kitchen, talk to Judy and get out of her apartment to complete this job.
