be in for
1. To anticipate or be very likely to experience something, usually that which will be unpleasant or undesirable. They just called another general meeting with the staff. It looks like we're in for more bad news.
2. To be involved with or a part of something for a particular reason or purpose. More usually "be in it for." I'm not really that concerned with non-profit work. I'm in for the boost it will give my career.
3. To be in prison or similarly detained for a particular reason. What are you in for? My brother is in for stealing a car.
