Carpe Noctem

While investigating the strange deaths of various men, who appear to have been drained of life energy, Angel finds himself in a bind when an old man switches bodies with him. Marcus, it turns out, is staying young by switching bodies with younger men. He ends up killing them as he carouses with booze and orgies. While Marcus enjoys himself in Angel's vampiric body, Angel tries to leave the retirement home in the frail Marcus's body to warn the gang of the impostor in their midst. Meanwhile, Lilah continues to clash with her co-worker Gavin over their tactics to take down Angel and his group.
