Movies, where a 3rd or more person was "forced" to join?

Hi, I´m searching for videos where a 3rd or more person joined the action. Could be after a while step by step like in the movie of the pic of this thread or could be after a little while going straight to it because of the Situation, that is forcing to act. You get what I mean?

For example the movie in the pic Smart House Of Horrors: Angela White was offered herself to help the couple after a while to get herself and the couple out of the situation. So she joined step by step the action.

Hope you guys understand what I´m searching for haha
