Batman is convinced by his family to take a night off of patrolling and watch a movie with them. But Gotham's crime never sleeps, so Bruce calls in a favor or two...
Tropes:
- Heroes Gone Fishing: The plot kicks off because the family convinced Bruce to stay in and watch a movie.
- Paper-Thin Disguise: Harley thinks that her homemade Batman cape and cowl are enough to convince people she's Batman...despite the fact that she's wearing her usual attire under the cape.
- Superman Stays Out of Gotham: Averted; Superman is invited to Gotham! Harley, on the other hand, disagrees, partially because she thinks she's the natural fill-in for Batman and Robin and partially because of this trope, saying that Gothamites are "allergic to truth and justice."
