No Good Deed

After a night on the town, two off duty cops get lost in an unfamiliar neighborhood. They stumble upon a house with the front door mysteriously open. The more experienced one, Ben, wants to investigate. The other one, Mark, thinks it's a bad idea. They're off duty, drunk and don't have their guns, but Ben convinces Mark to enter. The house is empty, the lights are not working and there is a very strange smell inside. When Mark wants to leave, Ben gives him a choice between abandoning his duty or doing a good deed.
