Let's solve the expression step by step:

Expression: 

\[
-3(-2)^3 - (-4)
\]

### Step 1: Evaluate the exponentiation
\[
(-2)^3 = -8
\]
So the expression becomes:
\[
-3(-8) - (-4)
\]

### Step 2: Multiply
\[
-3 \times (-8) = 24
\]
Now the expression is:
\[
24 - (-4)
\]

### Step 3: Subtract a negative
Subtracting a negative number is the same as adding it:
\[
24 - (-4) = 24 + 4 = 28
\]

### Final Answer:
\[
28
\]
