review text: In the paper the spatially flat Friedmann model containing a pressureless perfect fluid (dust) and a minimally coupled scalar field with an unbounded from below potential is studied. All exact solutions describe the recollapsing universe. The behaviour of the model near both initial and final points of evolution is analyzed. The evolution between big bang and big crunch crucially depends on the model parameters. It is shown that the model can be consistent with the observational parameters.
