Black Canary is called to lower Gotham to find out why people are disappearing. She sneaks into a warehouse with suspicious (more so than usual) happening around it and finds herself in an A.I.M. science lab on the Manhattan waterfront.
They tell her in order to get back home through their equipment she has to collect 5 items that were recently stolen and handed out to:
The scientists reluctantly (after she defeats their security team) give Canary a tracking device to find the pieces. It shows them scattered trough out Manhattan. It doesn't matter what order she retrieves the pieces and is only given the names of the people who have them.
Can she clear it? She'll only use her scream if she has to.
Oh yea, she only has 6 hours to do it then she's trapped in the M.U. till she finds another A.I.M. lab.
