When, after being revived from a near drowning, a devout little girl is plagued by nightly visits from an evil dwarf-like creature, (22) her two disbelieving teen brothers must convince their terrified, and missing, African housekeeper to help them find a way to banish it. (44)

There are too many strange and unrelated descriptions in this version. I take it the numbers in the logline are word counts, if so, best you remove them.

It reads as if the two brothers are the main characters, if this is the case, you only describe the first thing they do but not their main action in the film. Convincing the housekeeper to help is one little thing, actually doing something with said help is the main plot and still missing from the logline.

Secondly, there is a logic flaw in the descriptions of the housekeeper – how can he or she be missing if they know where he or she is and are able to convince him or her to help?

Lastly, is “…African…” relevant? And what is he or she terrified of?
