In "Alibi," a businessman hires a professional to kill his partner but then has trouble following through on the plan.
As the episode opens, Mark arrives at a dirty storefront and then goes into the back room. There, he meets Barney, who is willing to bump off Mark's business partner, Hannigan, for a thousand dollars. Mark offers to pay half up front and the other half afterward. He can't get all of the money...until his partner is dead. Barney agrees to the deal, and then gives Mark his instructions for a solid alibi that will protect him.
That evening Mark is supposed to go to a bar called The Pelican and talk to Barney's friend, Mr. Allen. When he does, he discovers that the bar is closed down! From that point on, Mark struggles to follow Barney's instructions for an alibi.
