Für den Deutschunterricht musste ich eine Inhaltsangabe zu dem Roman schreiben.
For German class, I had to write a summary of the novel.

The word is composed of 'Inhalt' (content) and 'Angabe' (statement/indication), connected by an '-s-'. It literally means an 'Angabe des Inhalts' (statement of the content), and thus describes exactly what it does.
Auf der Rückseite des Buches steht eine kurze Inhaltsangabe.
There is a short summary on the back of the book.
An 'Inhaltsangabe' (summary) is typically 'geschrieben' (written), 'verfasst' (composed), or 'erstellt' (created). In a school context, students are often also given the task of 'anzufertigen' (producing) a summary.
Die Schüler müssen eine Inhaltsangabe des ersten Kapitels verfassen.
The students have to write a summary of the first chapter.
To connect the summary with the work, you usually use the preposition 'zu' with the dative, for example 'eine Inhaltsangabe zu einem Film' (a summary of a film), or the genitive, for example 'die Inhaltsangabe des Films' (the summary of the film).
Ich habe online eine Inhaltsangabe zu der neuen Serie gelesen.

interpretation
'die Interpretation' and 'die Inhaltsangabe' often both come up with texts, films, or plays. An 'Inhaltsangabe' (summary) says briefly and factually what happens or what something is about. An 'Interpretation' explains what something can mean and how it is understood. Learners often confuse these words especially in school, because both can be assignments about a text. The important difference is: first summarize, then interpret. For the plot, use 'Inhaltsangabe'; for the meaning, use 'Interpretation'.
