Let me tell you the plot.
***** NOT A TEACHER

Hello, Kimijane:
IF I understand my books correctly, there are two ways to analyze that sentence. I shall TRY to explain both ways. Then you can decide which way YOU prefer.
Before I start, may I remind you of something that you probably already know?
Sometimes an infinitive has "to": I like
to read. ("I like read" is NOT acceptable.)
Sometimes an infinitive does NOT have "to": He made me
read. ("He made me to read" is NOT acceptable.) If an infinitive does NOT have "to," grammar books call it a bare infinitive.

First Analysis
You = understood subject (just as your students said).
let = verb.
me = object (of the verb "let").
tell you the plot = an infinitive phrase. (In other words: "
to tell you the plot." But after certain verbs, such as "let," native speakers use the bare infinitive.)
a. The infinitive phrase "tell you the plot" is the
objective complement of "me."
i. "Complement" comes from the word "complete."
ii. If you tell someone "Let me," she will ask you, "Let me what?"
iii. So you need something to "complete" the object "me."
iv. Thus: (You) let
me tell you the plot. (See how "tell you the plot" completes the meaning of "me"?)
(a) tell - infinitive.
(b) you = the indirect object
(c) the plot = the object of the infinitive "tell." (Compare: tell the plot to you.)
Second Analysis
You = understood subject.
let = verb
me tell you the plot. = infinitive phrase that is the object of the verb "let."
a. me = the subject of the infinitive "tell."
b. tell = the infinitive.
c. you = the indirect object.
d. the plot = object of the infinitive "tell."
Thus: (You) let
me tell you the plot. (See how "me tell you the plot" is the object of the verb "let"?)
James: You let.
Mona: I let what?
James: Me tell you the plot.
Mona: OK. Go ahead.
I know that it is very confusing. Don't hesitate to ask any questions that you may have. Other members (or I) will be delighted to answer.
