Night Screams (1987)

Somewhere in Wichita, Kansas, David is a potential college football star who's just won a four year scholarship to a (no doubt, nice posh) college somewhere in Oaklahoma. His mates decide to throw him a serious farewell party whilst his folks are out that night.

Unfortunatley three uninvited guests secretly gatecrash these nightly celebrations, two are convicts who've fled from lockup, now hiding out somewhere in the homes cellar, while our third interloper is a mental patient escapee, with a connection to the party guests and notably David himself. Before long homicidal rage resurfaces in one of these trio leading to a carnage filled rampage.
