Confused and hung over, Nadia tries to piece together what happened the night before. She tracks down Wardog, the drug dealer with the Israeli joints.

Meticulous as always, Alan steadies himself for a rendez-vous with his girlfriend. Meanwhile, Nadia's latest discovery sends her reeling.

Perturbed by the changes in his routine, Alan shows up at Nadia's birthday party. Nadia tries to make amends to John, and Alan confronts Mike.

Nadia and Alan try to figure out how they're connected. Alan can't remember his first death, so Nadia follows him over the course of his night.

As the present begins to unravel, Nadia's troubled past comes back to haunt her, and Alan worries they're running out of time.

Nadia and Alan look for each other and finally cross paths at the deli. Something's not right -- but they're not giving up on each other.
