Adapted by Tony Piccirillo from his stage play of the same name.

Smugly poised Dan (James Marsden, The X-Men) goes home with rumpled, mumbly Tom (Scott Speedman, "Felicity"), and the flirtatious banter gets awkward quickly. It transpires that the two had a one-night stand a few years back; Dan, apparently a slut, forgot. In the ensuing fog of embarrassment, Tom suddenly overpowers Dan, ties him up, and forcibly extracts a blood sample. Tom claims he's HIV-positive (he found out 24 days ago, hence the title) and Dan is the only man he's ever slept with. Dan maintains he's been tested many times and is negative.
