Xiao Wu’s existence revolves around school, an empty apartment and the dubious comforts of instant noodles. One day, his routine is subtly transformed by a tenant in the apartment, a stranger who is nursing a heartache. Their paths cross only once in a while, yet Xiao Wu dreams of a more intimate rendezvous. Longing for human contact, Xiao Wu tries all he can to make a connection through physical and metaphorical walls in that hour between night and day. Little does he know that his strange man to whom he finds himself drawn to is also in need of companionship. A meditation on desire and obsession, 4:30 is about a moment, and a boy’s attempt to cling to it, no matter what the cost.
