can 你 help me? please

i just made a movie, it's for a school project but i don't know how to name it.
the story goes like this: there is this guy who is a delivery guy, and in an apartment building he meets a weird clown but they don't talk. they just walk by. when the main guy gets out of the building he hears a noise (like a screaming) so he runs fast up the stairs to help the person in need...while running he sees the clown again who now is coming down the stairs, and again they don't talk to each other but the clown has blood in his gloves.
the main guy sees it but doesn't say anything, when he runs upstairs, he sees an open door so he gets inside the apartment and sees a dead girl lying on the ground.
he tries to help her but she's dead (she was stabbed and the 刀 is there on the ground) and he's holding and watching the bloody 刀 in panic when someone walks in and sees him... END
so now people are gonna blame the innocent guy for a crime he did not commit, sorry about the long text but please if 你 can, help me, what do 你 think the 标题 should be?
