The plan was as follows: Galiński would dress up as an SS guard and escort Zimetbaum through the perimeter gate, pretending he was escorting a prisoner to install a washbasin. Zimetbaum would be carrying a large porcelain washbasin in a way that hid her hair, so the guards they passed would not know it was a woman he was escorting. Galiński would show them a forged pass, and they would be let out. Zimetbaum would be wearing a pair of overalls over a dress that could pass for a men's shirt when inside the overalls. When they got far enough away, Zimetbaum would dump the washbasin, remove the overalls, and wear the dress, and they would pretend to be an SS guard and his girlfriend on a walk.
