While his girlfriend Annie is away for the weekend, 30-year-old Dave works fervently on his next big art project. Dave has for years had a habit of not being able to finish anything, and is apparently jobless as he still gets his income from his parents, whom he believes are tired of him. He finally has a breakthrough and begins to build something from the center and work his way out. When Annie comes home, she is surprised to find Dave's project: a small cardboard fort that is supposedly bigger on the inside. Dave, who communicates with Annie from the vents he added, tells her not to enter or destroy his project. When Annie shakes the exterior, she is confused by the abundance of noise and machinery she hears on the inside.
